When upgrading my clone of the Prusa mk2s to a mk2.5s, the original upper print fan support part did not work, because my stepper motors have a wire connector on them, and this must be wider than what the original Prusa motors have. I used Tinkercad to simply extend the reach of the original part, by 5.25mm. This now works perfectly. I sure hope this helps someone else too!
