Prusa Mini+ Base - Lazy Susan for filament spool

Update! Added a new model that adds a lip to the lower piece to add just a bit of drag to the spool so that it does not unwind too freely.

This is a lazy susan, or a rotating table to let the filament spool turn freely. Hanging the spool under the mini base as intended in the original design caused binding and tangling of the filament on mine. I designed a rotary table to let the spool turn freely, sitting beneath the printer for the compact footprint. It is two printed pieces and a skateboard bearing (8mm ID, 22mm OD, 7mm wide).

I printed in PETG, and put the bearing in the freezer, it will push in with a little bit of pressure.

Two models are included for the top half of the lazy susan, depending on the ID of your spool. Amazon Basics uses the 52mm top, while overture uses the 54mm. If you only want to print one, print the smaller one.

Can be printed without supports, and using .2mm layer height.
