Dry Box PTFE Port

PTFE tubing port designed for the Sterilite Dry Box (https://www.printables.com/model/271750-sterilite-dry-box).

Uses standard PC4-M10 pneumatic fitting, 4mm PTFE tubing and 10x3mm magnets. Note that the actual thickness of the magnets I purchased was 2.7mm.

In my case, I had to drill a 5mm hole on the "inside" of the PC4-M10 to allow the PTFE tubing to pass through.

Note the polarity of the magnets on the PTFE port and the PTFE holder. This way the PTFE holder can be installed facing left or right.

Push the PTFE tubing about 5-6 inches inside the dry box. This allows the PTFE tubing to guide the filament as the filament core reduces in diameter.
