These are printable parts for a 3D scanner turntable. The base has been designed to sit on top of a standard Nema 17 motor. The turntable plate and the modified ciclops gear are designed to fit on top of the base.
Step 1: Fix the knob to the motor shaft with a small screw.
Step 2: Fix the support plate on the motor body.
Step 3: Push the gear into the slots provided on the support plate. The stubs on the inside of the gear should be towards the bottom.
Step 4: Place the turntable so that it locks into place on top of the knob. You can fix the turntable to the side wings on the gear to make it more stable (however, if the gear does not move smoothly, this might make the turntable movements jerky and unpredictable).
