Dry Filament Box with Universal Auto Rewinder

thingiverse

This is my version of a redesigned filament drybox based on work from Greg (ea69), but I wanted to reuse Vincent Groenhuis' auto-rewinder hub/spring/clutch design and I wanted it to be bi-directional in the box housing. I also reviewed Spannerhand's designs and really appreciated some of their box design and wanted to incorporate some of those key features (clasp, PFTE bowden coupler) as well. Known Working Spools: Overture: 1kg 200mm dia. x 67mm width Ninjatek: .5kg 200mm dia. x ~73.5mm width Hatchbox: 1kg 200mm dia. x 68mm width 2020-08-11: Refreshed the loose desiccant chamber version for the plug fitting. It's tight but does fit. 2020-08-08: I've modified the filament box bottom to also provide a loose silica gel version. The desiccant holding volume is approximately 90ml, the grid hole diameter is 1.5mm targeting 2-5 mm beads. The Universal Auto-Rewinder components are included for the specific versions used here. See [Vincent's design](https://www.thingiverse.com/thing:3338467) for more details.
