Want a quick, firm, durable connection for your PTFE lines? For quick diagnostic, quick swapping, without afflicting much damage on the PTFE itself?

Want a universal connection that can act as an extender, terminal at the same time?

Want a near air-tight connection for little to no moisture?

You came to the right place, welcome to the UBBI

An open source design, which you can integrate anywhere freely, enhancing your ptfe game!

\ud83e\udd29 Do you like the design? You can help fund innovations like this!
Consider supporting me!
Much appreciation given to my supporters, and you get exclusive access to various CAD files!
Submit feature requests here!

Features:
- Supports both PC4-M10 and ECAS04 couplers
- Allows for 3mm max internal diameter PTFE tubing
- Only 1.6mm between tube ends, suitable for bowden setups, minimal drag
- One piece fits all, no female or male ends
- Prints with minimal supports
- Twist locking mechanism with audible snap
- 14mm wrench can be used to operate the piece

NOTE:
The first 3-4 snaps must be done with a wrench, to break in the mechanism before it gets soft enough to be used by hands!

For remixers: The UBBI made for remixing into other models is included in the .step file

All UBBI versions will be forward and backward compatible, all versions will click together! Beauty of continuity!

Avoid clear ptfe, natural ptfe is opaque, clear tubing is mixed and does not slide as smooth!

Recommended print settings:
- Nozzle diameter: 0.4mm
- Layer height: \u2264 0.2mm
- Reverse on odd: disabled
- Precise walls: enabled
- Wall order: i/o/i
- Tolerance requirement: 0.1mm
- Print orientation: as imported
- Supports: included with the model, enable support generation and change to manual placement, don't add anything

Recommended materials:
- PETG
- ABS/ASA

Installation requires:
- PC4-M10/ECAS04 (Remove silicone seal)
- 4mm OD PTFE tubing
*Note: 2mm ID for bowden system, 2.5mm ID for reverse bowden
