Update 10-nov-2018: improved the inner cap design and added an outside cap to close off unused feeders. Also included a 45 degree design
This is my take on a drybox feeder. I wanted a solution where the inside of the box is isolated from the outside, while still feeding filament. This is accomplished by inserting a sponge in the inside part of the feeder, and screwing the cap on while inserting filament. It's also possible to put some oil (WD40) onto the sponge to lubricate the filament a bit. It can then be fed into a PTFE tube which travels to your extruder.
Hardware required per feeder:
1x PC4-M6 bouwden coupler
2x M3x12 screws
2x M3 hex nut
2x M3 washer (optional)
PTFE tube
