Need a crank for a rotary encoder? Here's a print-in-place model that features a hinged arm and free-rotating handle. The pieces can not be disassembled. It's just one part that prints in about 20 minutes. Press fits over any flat nose rotary encoder, for those times where you need a cranky crank!
Fusion 360 model included with accompanying STEP file. User parameters are setup for tolerances, length, shaft diameter etc. Gap is set to 0.4mm in STL file. Check out the source for your own tweaks!
