Sunlu coupler - M6 pneumatic coupler
Added 2023-02-27 18:26:17 +0000 UTCThis actually took many tries to get it solid, but that one has held up over time, print orientation was key
I recommend PETG for its elasticity over PLA
print with at least 3 walls/perimeters
use a brim if print fails, as it's bridging a relatively thin piece, but worth trying without first.
Use a small piece of PTFE tubing (5~7mm should be enough)
