I designed this turntable to put into my filament dryer (aka food desiccant) so that I can feed the printer while running the drier. Just print the turntable, poke a hole in the plastic cover of the dryer and run a ptfe tube to your printer. You can then feed the filament through the tube and keep the dryer on while printing.
This is designed to be printed in a Prusa Mini and the size is big enough to hold standard size 1kg spools. The Fusion 360 file has a parameter to size the adaptor to fit the size of the inner circle of your spools.
This turntable uses 11mm ball bearings, but it should be pretty easy to modify for other sizes.
I recommend you print it in PETG so that it does not deform in the heat of the dessicant.
Happy printing!
