PC4-M10 PTFE Tube Connector Replacement

UPDATE!

A great designer, Weber, made a terrific A1 PTFE Tube Connector replacement that many users have been using to combine our models.  I recommend checking it out at these links!

I didn't want to buy PTFE connectors for a y-splitter I downloaded, so I wanted to design a reasonable replacement that was only a few grams of filament.  It's a tight fit to slide the tube in on purpose, but just work it in.  I also wanted to go further than hand tight, so I included a printable wrench for you to tighten it down a little extra, but you'll likely need an adjustable wrench or pliers to remove since it gets nice and tight.  It's meant to be used with the typical 4mm PTFE tubing that Bambu uses.  If you are using in a high torque application, I recommend printing in PLA-CF, PETG, ABS, or another high strength material to improve layer adhesion for the threads, but PLA worked great for my uses.  Remember, this is very low cost vs the metal alternative, so print extras if needed.  I hope you enjoy and let me know what you think!  Feel free to play around with the size of the nut that screws on top for a tighter fit.  You can use this to replace any PC4-M10 fitting as the threads are a match, so just print as many as you need!  See below for assembly instructions.

Screw the fitting into the “M10" port on your part

Slide the nut over the PTFE tubing

Push the tubing into the fitting (it's a tight fit, so work it)

Tighten the nut down with the provided wrench
