I created this carousel adaptor for my Anko dehydrator, so I could direct feed my printer.  There are two variants, one that fits 52mm ID spools and another that fits 55mm or larger.  Uses standard 608 bearings.  If the fitment seems a bit loose, just melt the ends a bit after inserting the bearing, and the deformation will keep the bearing on.

This sits on the thin lip of one of the trays, which must be fitted to the bottom first.  The baffle in the middle also must be removed.  It just pops right off.

This fits in conjunction with my Dehydrator spacer.

Printed in ABS.
