Thanks for checking out the Ultimate Bowden Tube passthrough!
This passthrough is a bit extra but I wanted an almost zero compromise solution for dry box builds.
Parts List:
For Bowden pass-through
- 2 x M3x12 FHCS (Flat-Head Cap Screws)
- 2 x M3 Heat set inserts (I used these)
- 1 x O-Rings 32mm OD 29mm ID 1.5mm Width (I used these)
- 1 x PC4-M10 Fittings for Bowden Tubes (I used these)
- 1 x Pass Through Printed Parts (PLA is sufficient and 3+ walls will be more airtight)
- PTFE Tube (4mm x 3mm) cut to your desired length (I used this)
