Dry-box Filament Pass-Through | PTFE Fitting

Description

A connector designed to optimize the passage of the filament through a dry box, requiring only a single 10-mm hole.

We’ve adopted the cable guide design. This means you can use a PTFE tube with an outer diameter of 4 mm and an inner diameter of 2 mm. You can add a TPU seal (Part III of the downloadable file), a silicone seal, or even an O-ring.
The tolerances between Parts I and II are optimized for 3D printing with a 0.4 mm nozzle. Extensive testing and adjustments have been carried out.

🏆No screws, no extra purchases, no hassle!

Just tighten it by hand. It's simple, effective, and more than enough to feed a PTFE tube through your watertight box!
