These are the CAD files for my recent project to build a mechanical counter from a dual Geneva drive. I've included .step files and the original Fusion 360 model if you want to CNC the parts. If you want to 3D print the parts .STL files are also included. You will need 6 bearings 10mm OD 4mm ID by 4mm thick and some 4mm shafts to complete this project. Any issues with these files let me know.
