VITULUS CAD files published
As a modeling software tool, I used FreeCAD, it's open source and powerful enough to do everything I need to do it. On my GitLab you will find both source files for FreeCAD and .stl files with individual parts for printing. There are all printable parts of the robot. Furthermore, only electronics, servos, connecting material such as screws, nuts, threaded rods and even bearings are needed.
You can use the source files for FreeCAD if you want to modify a component, or you can contribute some improvements or new accessories. The print files are designed for printing on a PrusaMk2 / 3 printer. That is, for a printing area of 21x25 cm. If you do not have a suitable printer, try prusaprinters.org (print on demand) and you'll probably find someone nearby who can print the parts you need. Alternatively, contact me by email and we will make an agreement.
The robot parts are divided by units.
