I ordered SEAL Lite scanner and a day after that - their turntable and tripod for scanner.

Before whole set was delivered - I started to play by myself and I designed needed stuff.
SEAL Lite (standard SEAL probably as well) came with a screw we can use with adapter, so you can use any other tripod if you have any.

For turntable suggest to use bearing in the center - but even without it, it should be fine.
Of course you need to turn the table by yourself during scanning an object. Using this model - you can save some money on these two thing from the shop.

I added 3 types of legs there - use only one and print it 4 times.
