Improved suspension and new coupling lengths
Please read!
A 0.2 mm nozzle is required, 0.1 mm layer height, no supports. I printed with PLA Basic from Bambu Lab in black. I recommend either using this or another well-calibrated PLA
Since there seems to be no standard for this type of coupling, this coupling does not fit every vehicle equally. There seem to be differences especially between manufacturers. On my vehicles, the magnetic coupling was tested for system use and continuously improved. Tractive effort is absolutely sufficient, 150 cm trains were pulled over a 1.5% incline without problems
Coupling distance
There are three different coupling lengths:
(S) Small
(M) Medium
(L) Large
The respective coupling length is printed on the underside of the coupling
Magnets
N52 magnets with 1.5mm diameter and 1.5mm depth are used here. I ordered the magnets here:

Assembly
For assembly, the magnets are fully pressed into the holes. Pointed pliers can be advantageous, as some force is required. No glue is needed
Compatible with Peho 333 magnetic couplings
