Boosting makers is free and helps us pay for the filament we use making prototypes. Please consider boosting me.
A better spool holder for the Polymaker dryer / Drybox and the Snapmaker Snapdryer.
I downloaded several and they all had some issues. The best were still the wrong size for the box, required glue on the bearings and the hubs to keep them from falling apart.
This one is a precise fit. It is assembled by press fit. The parts have a gradual taper so if your filament shrinks more or less than mine, you can still use it and you won't need glue for it to stay together.
Because it is inside a dryer/drybox, I suggest you use PETG or better if you also intend to use it as a dryer. If you only use your boxes as filament distributors like I do, it is fine to print it out of PLA.
It uses 608 ball bearings. The ones I use are here:

Any 608 ballbearing would work, including those I linked toon Bambu's site.
