I made a spool to make it easier to dry the silica gel containers in a filament dryer.

It's 156g when printed in ABS, 190g in PETG, but ABS or ASA are recommended.

Works best with 50mm silica containers. The spool has a diameter of 200 mm.

I designed it to be press-fit, but you might still need some glue.

I made it in Blender. I'm still learning, so if you want to redesign it, it's probably not the best base — starting from scratch might be easier. :D

Hope you find it useful!
