So you’re looking for the CAD download files…… Well E3D has finally released the files. You can find the files at their Github. https://github.com/e3donline/ToolChanger
E3D ToolChanger Assembled
The E3D tool changer files are published on github but if you’re looking for the assembled files or toolchanger assembly check out EJaworenko on Thingiverse here.
“E3D released their ToolChanger printer design to be open source! Exciting times. I went through the process of assembling the entire printer as a way of studying what they did and why they did certain things while designing a printer based off of it.” -EJaworenko
- Fusion 360 F3Z files
E3D ToolChanger Enclosure
Gregory Holloway published the enclosure design on Thingiverse along with many other E3D Toolchanger files such as the ASMBL Subtractive Tool. Greg’s laser-cut acrylic enclosure design is for the ASMBL Subtractive Tool. Check out Gregory’s Thingiverse here.
E3D ToolChanger Clones
While E3D has been perfecting their motion system and toolchanger design it take long for the clever engineering detectives that make up the Reprap community to reverse engineer the motion shystem. Makers have been developing tool changing techniques before E3D changed the game with their new machine. The concept has been presented in many ways but since the E3D MRRF 2019 presentation many inspired designs and clones have appeared. The best one that I have seen is by a Thingiverse User: TPRA.
First tests here :
Still work in progress :
“I’m releasing this now even if not definitive because people asked for it, but it’s still a prototype.” -TPRA

Kinematic Couplings / Mounts
Practical Precision demonstrates kinematic mount design and layout using the Maxwell criterion.
- The Maxwell criterion
- How to layout a kinematic mount using the Maxwell criterion
- Common kinematic mount layouts
- Challenging layouts – optical payload for a stabilized gimbal
- Stability and repeatability over micro assemblies and disassemblies
- Example of a poor layout for stability and repeatability
- Satisfying the Maxwell criterion for a planar kinematic mount
- Instantaneous centers of rotation and the kinematics of the mount
In this video Practical Precision demonstrates how to design and model a kinematic mount in CAD PP uses SolidWorks. Kinematic mounts are useful for precise mounting in highly accurate applications.
