This is a turntable system that you can create using on-hand resources and some 3D printing. You print the boxes and rollers, and you attach them to the piece of cardboard or wood of your choice. These rollers are adjustable for whatever size of plate as you have/need. The weight they'll support hasn't been tested yet, so if you print and use this system, let me know how it went. It will support an average weight. I just don't know for sure if it'll support anything super heavy. A video description can be found here:
