V-Minion - Render


Whilst many printers feature an ever-increasing build volume, the most common FDM prints are small. A smaller build volume means less moving mass, leading to faster and better looking prints.

Build Volume - Feature


Utilizing 3060 extrusion for its frame, the V-Minion is extremely sturdy. This allows for faster printing with lower vibration, all leading to better looking prints.

3060 Frame - Feature


The V-Minion features linear rails (MGN15H and MGN12C) on all 3 axes, providing smooth and quiet motion.

Linear Rails - Feature


The V-Minion features EVA as its extruder and hotend carriage platform. This means you can use a huge list of extruder and hotend combinations, outside of the ones we supply. There are many options. The great thing about EVA is that it will keep your printer open to updating: every year new hotends and extruders are released by so many amazing manufacturers. How cool is it that you get to simply re-print your print head and add a new hotend or extruder?

EVA is a project developped by Paweł Kucmus, read more about EVA in the official EVA project page.

EVA Modular - Feature


The V-Minion features a custom made, precision milled, 5mm bed plate designed for exceptional flatness and heat stability. Going one step further, we have worked directly with Keenovo, industry leaders in silicone heaters, to develop a bed heater which is both high performance, and safe due to its built-in thermal protection.

Bed - Feature

Bead Heater - Feature


All of the V-Minion electronics fit into the specially designed case. It has been designed to house the power supply, a Raspberry Pi, as well as your printer mainboard, all whilst providing cooling via a built-in 40mm fan. The default design supports the BTT SKR2, BTT SKR Mini and the BTT Octopus mainboards. The side panels are CNC manufactured from 4mm Polycarbonate, making them incredibly strong, but can also be printed if you prefer.

Case 1 - Feature
Case 2 - Feature


The on-frame spool holder is designed to complement the V-Minion. Based upon the same 30 series extrusion as the rest of the printer, it keeps your filament close-by and makes moving the printer a breeze because the filament comes with you.

Spool Holder - Feature


RatOS is developed by and in cooperation with Mikkel Schmidt especially for our printers. It combines the power of the Klipper firmware, as well as several other open-source projects, to provide a stable and easy-to-use operating system for all your printing needs.

The V-Minion has a comprehensive step-by-step build guide in both static and animated forms. Each section is broken down into easy to follow steps, detailing the parts needed and how to assemble them. A fully animated build video is also provided, should you wish to see exactly how each part is designed to fit together.

Build Guide - Feature


These images showcase 3D prints produced by V-Minion machines belonging to members of our community.





The V-Minion is an open-source project which is a result of countless hours of collaboration between our design team, the 3D printing community, and our beta team, all of whom share their knowledge freely to help push the 3D printing space forward as a whole. Being developed by using such a vast array of knowledge means that it is difficult to trace back any one idea, thus making attributions difficult at best. Regardless, we would like to acknowledge the following people and projects for their contribution to the V-Minion. They are as follows (in no particular order):

  • Paweł Kucmus
  • João Barros
  • Eduardo Oliveira
  • Tomasz Paluszkiewicz
  • Mikkel Schmidt
