This is a replacement coupling hook&spring for Playmobil wagons.
Printed in ABS the spring is stiffer than the original Playmobil piece, but that also means the wagons are less likely to accidently uncouple.
The uncouple-lever was left out and overhang angles are relatively small, to allow printing without support.
The third photo is a comparison between the printed part and the original Playmobil coupler (which has a worn out spring).
Update 2021-12-26:
The first version of this coupler was printed on a TEVO Tarantula with cheap ABS. This caused the mounting hole to be undersized, that is why in the SCAD/STL the mounting hole is bigger than normally necessary so that my old print setup produced the correct geometry.
Now that I have a Prusa printer and Prusament the part prints more accurately. I had to modify the geometry so that the mounting hole fits again. I have uploaded the revised version of the coupler: playmobil_kupplung_v2
The 3rd and 4th photo shows the newly printed part. This is printed in Prusament ASA white.
I also added the GCODE for the new coupler. This prints 2 couplers in ASA with 0.1mm layer height for better stability.
