Designing & 3D-Printing Magnetic Couplers for G-Scale Trains – A Satisfying Click!

[GAP]

I am using PETG but may explore ASA too. PETG is weather resistant and far less brittle than PLA. i am currently waiting for magnets to build non-polarised version - will update once i have one developed.

Are the ones that have the poles on the side instead on the faces?
I have just moved to PETG but have shied away from ASA because of the fumes (inside the house) and the need for an enclosure

so i sourced some 5x5x3mm N52 magnets and re-designed couplers






These are non-polarised, and i will test them on the track. They do look ok-ish, and much stronger than version 1 too.

I tried to print in ASA - but not big success, wrapping for small parts is too noticeable. so i'll stick with petg hf for now. the new design in the post above

I. thinking about PETG CF (Carbon Fibre) for hard wearing parts like my points and wheels
What CAD are you using?
