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.

Files description

Base_plate. Rectangular base with attachments for worm and worm gear.

Worm. Rod with teeth, driving the worm gear, and threads attaching a worm knob.

Worm_turning_knob. Round handle with a notch that attached to the worm with threads.

Worm_gear. 60 teeth gear, driven by the worm, and placed on the base. Attaches to the scanning table with threads.

Scanning_table. Circular base for objects for 3D scanning. Attaches to the worm gear with threads. Updated on 23-04-2024 to increase space (+ 5 mm) between the worm bracket on the base plate and the scanning table.
