A 3D printable alternative to the standard PC4-M6 and PC4-M10 bowden connectors. My design uses a simple screw in clamping mechanism to lock the PTFE tube into the connector.
I created this as a companion to my Reverse Bowen Tap.
I've found it to be an acceptable substitute that should save you time and money, hope you do too! Enjoy!
A simple design consisting of a base and clamping nut. The nut is common to both the M6 and M10 bases and comes in a standard and tall spiked head. The taller head is easier to tighten and the standard provides a minimal implementation/footprint. There are two versions of the M10 base with one allowing for the PTFE tube to be pushed through the entire base. UPDATE[20-05-31] Added a hex head nut variant.
Slide in a fastening nut through a 4mm PTFE Bowden tube with the threads facing the end that you want to connect.
Push the PTFE tube into the base fitting with the X cutout.
Screw the nut into the base to secure the PTFE tube.
You can now fit the base onto your desired bracket, or my Reverse Bowen Tap. You could also secure base first and then follow steps 1 – 3.
If you love this design and found that you no longer need to buy Bowden connectors then do feel fee to buy me a coffee, it would be appreciated!
Threads work well using 0.20mm layer heights using PETG.
You won’t need any supports, just follow the print orientation in the supplied image.
