Lego 12V Train Wheel Replacement

When 2 out of my 4 12V motors from the mid 80's suffered from breaking wheels around the center hole I designed this replacement part.

On these motors, all 6 wheels are the same, even the 2 ones in the middle, that are not driven. With a bit of force and good pliers it is possible to pull out the center pin, and to press it into this replacement.

I printed with 0.3mm nozzle and 0.2mm layer height - 18 min to print
