Filament dry box with universal hub and quick mounting system

I really enjoyed these dryboxes solutions but encountered some problems with spools getting tangled after they roll over itself. So I decided to give it a go and designed a new universal hub (tested with 50-72 ID mm spools) with spool hanging off center, which prevents excessive spinning while maintaining low friction. Additionally, added some quick mounting system which makes reloading easier. I often find myself changing spools from dryboxes to AMS and vice versa, and that made it significantly more comfortable for me. The hub sits loose but won't fall out from the spool (it was designed this way on purpose). Print the hub laying flat with manual normal support as shown in the picture. The arm is fetched and remixed from @tcosta_240835 design, so print the frame from his design.
