Use two 608Z bearings, four M3x20 DIN 912 screws and one 8mm rod (can be harvested from prusa printers after print) and make croissants like a pro :-)
All parts are in one STL for visualisation purposes, use “Split to objects” command in prusa slicer to split parts to individual objects.
I suppose general opinion is FDM prints are not food-safe for possibility of bacterial growth inside cavities, so please be careful, so wash it properly and disinfect it before next use.
