Intro
This is a Geneva drive that can change size, thickness and #steps by changing spreadsheet. The inspiration comes from both Kens12 and from MangoJelly - Thank you !!
Design
Open model in FreeCAD then update yellow cells in spreadsheet as required.
Sometimes FreeCAD complains, then save and close the model and then open it again, it usually works if your input values are reasonable.
The margin between wheels and also holes and pins is set with parameter distanceWheel.
a, b and c makes up a triangle that controls the entire design.
Printing this model is not so exciting, please feel free to use it as component for some other project, or print it BIG and add a crank.
Attached model is tiny, just 10 mm radius and 10 steps on wheel, parts are 1 mm thick. If your printer is not very accurate please scale it up in size.
