PTFE Y Splitter - No Additional Couplers Needed!

I’m very excited to share my first ever functional design. I'm definitely not an expert, I'm still learning a lot about 3D modeling and printing, so this was a big practice project for me. It might have some small errors or issues, but it’s working pretty well for my setup.

I noticed that almost all Y-splitters out there either use extra PTFE couplers or they just have a simple hole where the tube can easily slip out. So after checking out a bunch of models and ideas, I came up with this design, it has a built-in, fully 3D-printed coupler.

• No Extra Parts Needed: You don't have to buy metal couplers.
• The design uses a printed thread and a nut to securely lock the PTFE tube in place, so it won't come out

Printing & Assembly Tips:

• Orientation: Print the model vertically, exactly as configured in the provided .3mf file. This ensures the threads and internal paths are printed with the highest accuracy.
• Tube Insertion: When installing your PTFE tube, make sure to apply enough force to push the tube until it hits the internal stopper. This prevents any gaps where filament could snag.
