I had trouble with screwing in “PC4-M10” couplers into other models. Then I looked closely at the threads of the couplers and noticed a taper, which made me realize that PC4-M10 couplers don't actually use M10 thread; they use 1/8 NPT pipe thread.
So I made this coupler with the correct thread, and these work very smoothly.
Just screw the coupler until it bottoms out, then back it up by a turn, insert a Bowden tube on one side until it bottoms out, and tighten it up (using a wrench if you need to). Do the same for the other side of the coupler and you're done!
The model includes sequential bridging so there's no need for supports
