About this model

Joe3020 fitted an adapter for 10MM bearings for Overture cardboard spool, I remixed it to work on most spool holders. This adapter to insert into certain cardboard spools to reduce the amount of cardboard dust from spinning against the spool holders. Fits at least Overture, Inland (Microcenter), Duramic & Polymaker cardboard spoolsOD of the holder is 54.5mm so should fit spools that have about a 55mm opening.ID (hold within the model/part) is 45mm so will fit most spool holders.For PROTOPASTA, scale to 96%, it will fit the 52mm opening of protopasta/protoplant spools.No supports needed; recommend PETG for prolonged use (especially if in a heated enclosure) but PLA works just fine as well outside of that
