This is an inexpensive turntable for taking photos or videos or 3D scans. If you use the 200mm platform, the only thing you might have to buy is the Turn Table Motor for about $10. If you want to use your own platform, like a piece of wood cut to your specific size, then you'll need the 608-zz ball bearings so the platform stays level and turns easily. Because the turn table motor shaft is offset, you'll need a platform that is as least 340 mm in diameter.
I used the Qlone app to take 3D scans. They take about a minute to scan the entire item. You do have to pay to export the 3D scan.
You'll need: (affiliate links)
Turn Table Motor - 2.5-3RPM $10.99
608-zz ball bearings $8 for a 10pack
switch if you don't hardwire the electric motor to the cord
superglue or screws to attach the mounts to your own platform
paper clip or someway to secure the motor to the adapter (I've used a twist tie from a loaf of bread)
*optional and a bar of soap to lube the arms so they'll slide into place a bit easier
The turn table motors are not designed to operate all the time. They do get warm if left on for extended periods of time. When you turn them on/off the direction they turn changes.
Supports are only needed on the legs to provide support for the ball bearing posts.
I usually opt for more walls than infill percentage. These were mostly done with 4-5 walls as well as top and bottom layers.
