 If you want to contribute to this project, test or modify the CAD model, we recommend the following FreeCAD version and workbenches. [FreeCAD (Link branch by realthunder)](https://github.com/realthunder/FreeCAD/releases/)
 For the assembly process we've used the Assembly3 workbench. The workbench is bundled in the fork mentioned above, no additional installation is required.
