Magnetic connector for PTFE tubes:
The author remixed this model.
Initially, It was the only remix I found with a screwable M6 thread. But I sourced 5x5mm magnets, so I started to modify the model. I preserved the thread and did new holes, but ended up with something too thick: the thread was entering half way only when fully screwed in.
So I started over. This new version is flat, for 5x5mm round magnets and PC4-M6 couplings.
