Drybox Filament Pass-Through

###Yet another filament pass-through

#####Update 09.10.2019 - Changed inner diameter of PTFE Tube Cap to 4,2mm for a tighter fit on PTFE tube

I've created a filament pass-through that feeds the filament from inside the drybox into a PTFE tube.

####Printed Parts:
* Outer Feeder - PTFE tube is guided through the PTFE connector fitting to the Inner Feeder
* Inner Feeder - two types:
* Type 1 consists of the Inner Feeder and has an outer thread to screw the Inner Feeder Cap on - offers the possibility to use a sponge on the filament
* Type 2 - if you don't need the sponge, you can directly feed the filament through the filament cutout of the Inner Feeder into the PTFE tube - no cap needed
* PTFE Tube Cap - to seal a pass-through that is currently not in use.

####Needed Parts (for one pass-through assembly):
* PTFE tube (4mm OD, 2mm ID)
* 1x PC4 PTFE push-in connector fitting
* 2x Socket Head Cap (Allen) Screws M4 (length as you need)
* 2x M4 nuts
* optional: piece
