This is the baseplate for the splitdoor holder for a Hobby carvan. This thing would have cost me 70EUR, but no, I grabbed freeCAD and modeled a replacement myself. Should be good to go.

I printed it at 0.2 with a 0.4nozzel and 4 walls with a bambulab P1S printer, white PLA. Should be sturdy enough.
