Summary

The goal of this project was to make a simple 3D printable turn table for 3D scanning of small objects.
The model is hand-driven, by turning a knob that drives a worm drive with an attached scanning table. For 3D scanning using Photogrammetry, the notch in the knob can be used to estimate the revolution of the scanning table. For a full 360 degree revolution of the scanning table, the knob has to be turned fully for 60 times.
To obtain a high gear ratio, I used a worm drive instead of spur gears. I followed the tutorial by Igor Gaspar from My Tech Fun to model a worm(screw) and worm wheel (or gear). The five parts in this model were designed using the ‘Not for commercial use’ free version of Autodesk Fusion 360. I used an offset of -0.2 mm for parts such as rotating bodies, gear teeth, or threads. The five parts can be printed without supports.
