Turntable Photo-Scanner

3D scanner turntable

This minimalist turntable can be used for 3D photo scans. The object to be scanned is placed on the plate and can be photographed from all sides by simply turning the crank. Using the appropriate software, the images can be computed into a 3D object. You can find appropriate programs searching the term "photogrammetry".

The turntable was designed in such a way that it can be produced with as little material (PLA or PETG) as possible. Any 3D printer should have the additional parts needed. I used an axle (aluminium tube with 8 mm outer diameter and wall thickness 1 mm) and 2 roller ball bearings (outer diameter 22 mm, inner diameter 8 mm, width 7 mm) from a simple filament roller holder.

For the turntable you need a piece of aluminium tube that is between 3.8 and 4.2 mm long. For the crank, the aluminium tube should be between 4.5 and 5.0 cm long.

Press the two ball bearings into the recess provided in the plate.
