Top 10 Must-Print Mods for Voron V0.2 — 2025 Edition

V0.2 Mods Upgrades

The Voron V0.2 is a marvel of compact engineering — a 120mm cubed CoreXY printer that fits in a backpack but delivers print quality that rivals machines five times its size. But what makes the V0.2 truly special is the modding community. Despite its small footprint, there are dozens of well-designed mods that fix the printer's few shortcomings and expand its capabilities considerably. We've tested and ranked the 10 mods that every V0.2 owner should print. Last updated: May 2025.

This list focuses on functional mods — anything that improves print quality, usability, or expands the printer's capabilities. We've excluded purely cosmetic mods (colored skirts, decorative panels). Each entry includes what the mod does, why you need it, where to find the STLs, difficulty level, and estimated cost. Build plate is 120mm, so keep that in mind for print orientation. Let's dive in.

1. Belted Z Mod (Z Height Extension)

What it does: The Belted Z mod replaces the stock V0.2 lead screw Z axis with a belt-driven system, typically using a GT2 belt and a printed gear reduction. This eliminates the threaded rod entirely, converting the Z motion to a smooth belt drive that can extend the build height from the stock 120mm to 150mm or even 180mm depending on the design.

Why you need it: 120mm of Z height is the V0.2's biggest limitation. Many useful prints — keyboard cases, phone stands, small enclosures, and 40mm fan ducts — exceed 120mm. The Belted Z mod gives you 25-50% more build height without changing the printer's footprint. It also eliminates Z-wobble from imperfect lead screws and reduces Z-axis noise. The belt-driven Z is smoother, more repeatable, and doesn't need the anti-backlash nut that the stock lead screw requires.

STLs: Voron User Mods GitHub — search "V0.2 Belted Z" or "V0.2 Belted Z Mod". Multiple versions exist; the most popular is the "V0.2 Belted Z v2" by timmit99. Also available on Printables. Difficulty: Hard (4/5). You'll need to disassemble the Z assembly, print about 10 parts, and source GT2 belts, pulleys, and bearings. Cost: $8-15 for belts, pulleys, and bearings. Print time: ~8 hours for all parts. This is the most impactful mod you can do for the V0.2 — start here.

2. Mini Stealthburner / Dragon Burner Toolhead

What it does: A compact, lightweight toolhead replacement for the stock Mini Afterburner. The Mini Stealthburner brings the iconic Stealthburner look to the V0.2, while the Dragon Burner is an open-source alternative optimized for the V0.2's small gantry. Both use a single 4010 or 5015 part cooling fan for a lighter toolhead with better cooling.

Why you need it: The stock Mini Afterburner has adequate but not great part cooling, and the toolhead is heavier than necessary. A lighter toolhead means higher accelerations, less ghosting, and better print quality at speed. The Dragon Burner, in particular, is ~15g lighter than stock and delivers 30-40% more part cooling airflow. It also supports a wider range of hotends (Dragon, Revo Voron, Rapido) and probes (Klicky, Euclid, Beacon). If you're printing PLA or PETG on the V0.2, the improved cooling makes a dramatic difference in overhang quality and bridging.

STLs: Voron User Mods GitHub — search "Mini Stealthburner V0.2" for the official version, or "Dragon Burner V0.2" for the lightweight alternative. Printables also has several variants. Difficulty: Medium (3/5). Requires disassembling the stock toolhead and re-routing the hotend wiring. Cost: ~$1 in filament. Print time: ~4 hours for all parts. Print in ABS or ASA — the toolhead area gets hot from the heater block.

3. Side-Mounted Filament Spool Holder

What it does: A printed bracket that relocates the filament spool from the top of the V0.2 frame to a side-mounted position, either on the left extrusion or on a standalone floor stand next to the printer.

Why you need it: The stock V0.2 places the spool on top of the frame, which makes the printer significantly taller (adding ~150mm above the frame) and raises the center of gravity. With a full 1kg spool on top, the printer becomes top-heavy and more prone to vibration during fast prints. A side mount lowers the center of gravity, reduces vibration, and lets you fit the printer in tighter spaces. It also makes filament swaps easier — you don't have to lift the spool over the top of the printer. Some side mounts even include a reverse Bowden tube guide for smoother filament feeding.

STLs: Voron User Mods GitHub — search "V0.2 Side Mount Spool" or "V0.2 External Spool Holder". Many designs use a simple bracket with a 608 bearing for smooth spool rotation. Difficulty: Easy (1/5). Print the bracket, add a bearing, and bolt it to the extrusion. Cost: ~$0.50 in filament + $1 for a 608 bearing. Print time: ~2 hours. Nearly zero-cost and immediately improves both stability and convenience.

4. V0.2 Handle / Top Hat

What it does: A printed handle that attaches to the top of the V0.2 frame, or a "top hat" extension that serves double duty as a handle and a Z height extension for enclosed prints. Some designs integrate a Bowden tube guide and filament feed hole.

Why you need it: The V0.2 is designed to be portable — it fits in a camera bag or large backpack. Without a handle, carrying the printer means either gripping the bare extrusions (uncomfortable and puts pressure on the panels) or cradling it from underneath (risky for the electronics bay). A handle gives you a secure, ergonomic grip point. The top hat variant also provides clearance for prints that exceed the stock Z height (useful even without the Belted Z mod) and can enclose tall prints for better ABS printing conditions. If you attend printer meetups or move your V0.2 between home and office, this mod is essential.

STLs: Voron User Mods GitHub — search "V0.2 Handle" or "V0.2 Top Hat". Several designs exist — choose a simple handle if portability is your priority, or a top-hat handle if you want the extra Z clearance. Difficulty: Easy (2/5). Print 2-4 parts, add M3 hardware. Cost: ~$1 in filament + $2 for M3 T-nuts and bolts. Print time: ~3 hours. Print in ABS or PETG for strength.

5. Zero Click / Klicky Probe

What it does: A micro-switch-based Z probe that mounts on the toolhead and deploys only during bed probing, retracting out of the way during printing. Zero Click is the V0.2-specific variant optimized for the small build area and Mini Afterburner toolhead. Klicky is the original design that also works with some modifications.

Why you need it: The stock V0.2 relies on an inductive probe (PL-08N or similar) for Z probing. Inductive probes have limited accuracy on a small bed — they can drift with temperature, have inconsistent trigger points across the bed surface, and don't work well with spring steel PEI sheets (the inductive sensor needs metal beneath the surface). A mechanical probe like Zero Click gives you ±0.01mm repeatability regardless of bed surface type, works with textured PEI, PEO, and Garolite, and doesn't drift with temperature. For a printer as compact as the V0.2, the small bed makes precise Z probing critical — a few microns of error are a much larger percentage of the print volume than on a large-format machine.

STLs: Voron User Mods GitHub — search "Zero Click V0.2" or "Klicky V0.2". The Zero Click design is specifically made for the V0.2 Mini Afterburner toolhead. You'll also need to print a dock mount for the probe body. Difficulty: Medium (3/5). Requires wiring a micro-switch and configuring Klipper's probe parameters. Cost: ~$0.50 in filament + $3 for a micro-switch and wiring. Print time: ~2 hours for the probe and dock. Print in ABS for dimensional stability in the enclosure.

6. V0.2 Display Mount

What it does: A printed bracket that mounts a mini12864 display, Fysetc Mini12864, or a small touch screen (like the BTT TFT35) to the front extrusions of the V0.2, giving you local control without needing to open the printer's web interface.

Why you need it: The stock V0.2 has no built-in display — you control it entirely through Mainsail/Fluidd on a web browser or SSH. While this works fine for most users, a physical display is useful for quick operations: checking bed temperature before starting a print, pausing a print without grabbing your phone, or monitoring status at a glance. The V0.2's small frame means the display needs a dedicated mount that positions it cleanly without blocking access to the build plate. A well-designed mount sits flush with the front skirt, looking like it came from the factory. Some mounts also include a USB port access hole so you can plug in a flash drive for on-the-fly file transfers.

STLs: Voron User Mods GitHub — search "V0.2 Display Mount" or "mini12864 V0.2 Mount". Some are designed for the stock mini12864, others for the Fysetc version. Check the description for display compatibility. Difficulty: Easy (2/5). Cost: ~$0.50 in filament. Print time: ~2 hours. The display itself costs $15-25 if you don't already have one.

7. USB / Display Port Mod

What it does: A printed front-panel insert that brings the USB port, HDMI port, or SD card slot from the Raspberry Pi (or other SBC) to a convenient position on the V0.2's front skirt or side panel, so you can access ports without opening the electronics bay or reaching behind the printer.

Why you need it: The V0.2's electronics are mounted underneath the printer in the bottom chamber. The Raspberry Pi's USB and HDMI ports face the back or side, making them awkward to access once the printer is assembled and placed on a desk. Every time you need to plug in a USB flash drive with new G-code, connect a webcam, or flash firmware via SD card, you're either tilting the printer or reaching into a cramped space behind the desk. A front-panel port mod brings the most-used ports to the front where you can reach them easily. Some designs include a small USB hub for connecting multiple devices (webcam, flash drive, ADXL345).

STLs: Voron User Mods GitHub — search "V0.2 USB Port" or "V0.2 Front USB". Most designs are specific to the Raspberry Pi Zero (common in V0.2 builds) or Pi 4/5. Use USB and HDMI extension cables to route from the SBC to the front panel. Difficulty: Easy (2/5). Cost: ~$0.50 in filament + $5-10 for extension cables. Print time: ~1.5 hours. A small quality-of-life improvement that pays off every time you interact with the printer.

8. V0.2 Bottom Skirt Fan

What it does: A printed bracket that mounts a 40mm or 50mm fan inside the V0.2's bottom skirt, providing active cooling for the mainboard, stepper drivers, and Raspberry Pi located in the electronics bay.

Why you need it: The V0.2's electronics bay is a confined space with limited airflow. During enclosed ABS printing, the chamber temperature can reach 40-50°C, and the electronics bay (which is partially inside the enclosure) can get significantly hotter. Stepper drivers (like the TMC2209 or TMC5160) derate their current above 70°C and can skip steps or shut down if they overheat. The Raspberry Pi throttles at 80°C. A dedicated skirt fan pulls cool air from outside the enclosure across the electronics, keeping temperatures within safe limits. This is cheap insurance — a fried stepper driver or Pi costs much more than a fan and a few cents of filament.

STLs: Voron User Mods GitHub — search "V0.2 Skirt Fan" or "V0.2 Electronics Fan Mount". Most designs fit a 40x40x10mm or 40x40x20mm fan in the front or side skirt. Difficulty: Easy (2/5). Cost: $3-8 for a 40mm fan (Noctua NF-A4x20 or similar) + ~$0.50 in filament. Print time: ~2 hours. Wire the fan to a 24V output (use a buck converter if your fan is 12V/5V) or configure a Klipper controller_fan to run it automatically when the printer is on.

9. LDO Motor Cover / Dress Up

What it does: A set of printed covers that snap or screw onto the exposed stepper motors on the V0.2's gantry. Covers the A/B drive motors (mounted on the rear extrusions) and optionally the Z motor, giving the printer a clean, finished appearance and protecting the motors from accidental contact.

Why you need it:The V0.2's motors are fully exposed on the rear of the frame. This is fine functionally — stepper motors run cool enough and don't need airflow — but it leaves the wiring terminals and motor windings open to accidental bumps, loose filament strands, or curious fingers. The covers serve two purposes: they protect the motors from physical damage and debris, and they give the printer a polished, professional look. The LDO-specific variants are designed to fit LDO's V0.2 kit motors exactly, but generic versions work with most NEMA14 and NEMA17 motors used in V0.2 builds. Some designs include cable management channels for the motor wiring.

STLs: Voron User Mods GitHub — search "V0.2 Motor Cover" or "LDO V0.2 Dress Up". Printables and Cults3D also have several stylish variants. Difficulty: Very Easy (1/5). Print and clip on — no disassembly required. Cost: ~$0.50 in filament. Print time: ~2 hours for the set. This is a quick aesthetic upgrade that takes minimal effort and filament. Print it while you're working on something more complex.

10. V0.2 Camera Mount

What it does: A printed bracket that mounts a Raspberry Pi Camera Module, USB webcam, or OV5640 camera inside the V0.2 enclosure, typically positioned in a top corner or on the front extrusion for a clear view of the build plate.

Why you need it: The V0.2's small build area makes it hard to fit a camera. A standard tripod mount or desk stand doesn't work inside the enclosure. A purpose-designed camera mount secures the camera rigidly inside the printer, giving you a first-person view of the print for remote monitoring and timelapses. With Mainsail or Fluidd's webcam integration, you can check print progress from your phone, review failed prints, and create awesome hyperlapse videos of your builds. A camera is especially useful for the V0.2's typical use case — printing small, detailed parts where a failure can happen quickly and waste hours of print time.

STLs: Voron User Mods GitHub — search "V0.2 Camera Mount" or "V0.2 Webcam Mount". There are mounts for Raspberry Pi Camera V2/V3, USB endoscope cameras, and Logitech C270/C270-style webcams. Check the camera compatibility before printing. Difficulty: Easy (1/5). Cost: ~$0.50 in filament. Cameras range from $15 (Pi Camera) to $40 (USB webcam). Print time: ~1.5 hours. Position the camera so it has a clear view of the entire build plate without blocking the gantry movement.

Honorable Mentions

A few more V0.2 mods that didn't make the top 10 but are worth exploring:

• V0.2 Filament Guide: A small printed arm that guides the filament from the spool to the extruder with a reverse Bowden tube, preventing filament tangles and ensuring consistent feeding. Cost: ~$0.25. Difficulty: Very Easy.
• Panel Clip Quick-Release: Tool-free panel clips for the acrylic/enclosure panels, letting you remove any panel in seconds without unscrewing M3 bolts. Cost: ~$0.50. Difficulty: Easy.
• Skirt Cable Management: A printed clip or comb that routes the USB, power, and display cables neatly along the bottom skirt, preventing cable snags and keeping the desk clean. Cost: ~$0.25. Difficulty: Very Easy.
• LED Strip Mount: A diffused LED strip mount for the top frame extrusion, giving you illuminated prints for monitoring and aesthetics. Cost: $1 in filament + $5-10 for LEDs. Difficulty: Easy.

Installation Tips for V0.2 Mods

• Print in ABS or ASA: Despite the V0.2's small size, the enclosure can reach 45-55°C during ABS printing. PLA parts will sag and deform over time. Use the same filament brand and color as your frame parts for a cohesive look.
• Watch your clearances: The V0.2 has very tight tolerances. Measure twice, print once. A part that's 0.5mm too thick can rub against the gantry or limit Z travel.
• M3 hardware is your friend: Most V0.2 mods use M3 screws, T-nuts, and heat-set inserts. Keep a well-stocked M3 hardware kit. Voron-standard screws are M3x8, M3x12, M3x16, and M3x20.
• Test before committing: Try fitting a mod with dry assembly before applying threadlocker or final tightening. The V0.2's compact frame means a misaligned part is harder to fix than on larger printers.
• Document your mods: Keep a list of every mod installed, the STL source, and the print settings. When a part eventually needs re-printing, you'll thank yourself for the notes.

The V0.2 is already a fantastic printer out of the box, but these mods transform it into something truly special. Start with the Belted Z mod for expanded capability, add the Dragon Burner for better print quality, and work through the rest as you find time. Each one makes this tiny printer more capable, more reliable, or more pleasant to use. That's the beauty of the Voron ecosystem — no printer is ever truly finished.
