This roller assembly is ONLY for the Amazon cereal boxes with the hexagon shape on the lid.

This will not fit other cereal boxes. 

Works well printed in PLA or PETG. This system has an optional desiccant tray. Choose either the louvered or perforated lid. Tolerances are intentionally tight so you may need to lightly tap some parts together.

Uses 4 608ZZ bearings and a round hygrometer. The bearings from Bambu Lab Makers Supply seem to be higher quality than most of the Amazon options.

You can also use print-in-place bearings instead of steel but they are not as smooth and you will have more play in the finished assembly.
