Dry Filament Box with Universal Auto Rewinder

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 for more details.

The parts list for each box:
12x - M3 (.5) x 6mm socket head cap screws
2x - Desiccant Packets
or ~90 ml 2-5mm loose desiccant beads
1x - PC4-M10 Male PTFE Tube Push In Quick Fitting Connector
1x - TAIWEI Digital Electronic Temperature Humidity Meter

In addition, for the Universal Auto-Rewinder Hub, you'll need the two bearings like the 625-2RS from the MMU2S buffer design.

REVISIONS:

2020-08-08: Added loose silica gel option
