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.
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.
The parts list for each box: 12x - [M3 (.5) x 6mm socket head cap screws (https://www.amazon.com/gp/product/B07CJ7PDYT) 2x - [Desiccant Packets] (https://www.amazon.com/gp/product/B01LZAQPEY) 1x - [PC4-M10 Male PTFE Tube Push In Quick Fitting Connector] (https://www.amazon.com/gp/product/B01KHN1HWY) 1x - [TAIWEI Digital Electronic Temperature Humidity Meter] (https://www.amazon.com/gp/product/B07NSYQQGC)
In addition, for the Universal Auto-Rewinder Hub, you'll need the two [bearings] (https://shop.prusa3d.com/en/mmu2mmu2s/592-bearing-625-2z.html) like the [625-2RS] (https://www.amazon.com/625-2RS-Bearings-5x16x5mm-Miniature-Pre-Lubricated/dp/B07KTBCP4B) from the MMU2S buffer design.
