I will never buy Bambu filament again, so I needed a use for the re-usable Bambu spool.

Since I'm never gonna buy a spool from Bambu Labs ever again (because reasons) I needed to make use of their re-usable spool.
Align the little cutout with the nub on the spool and push it down. It's a snug fit but no problem to remove later. Fill the compartments with however much desiccant you want and put it in your dryer of choice.
After drying, attaching the lids on compartments makes it easier to pour out.
Note: The lid rim is 0.1mm larger than the hole it snaps into. This is because PETG usually shrink small features more than big ones. If this is produces a problem for you, size the lids down 0.2% or so and try again. Or use the CAD or step files to modify the lids if you want.
The lids store in the compartments when not in use, so no lose parts anywhere.
Printing:
Use PETG or something with even higher heat resistance, like ASA. If you use PLA you'll have a bad time drying the desiccant.
3 perimeters/walls minimum
.2mm layer height (other layer heights are perfectly fine but set precise Z-height to enabled if you do)
