Thank you for your fast reply. It must be a problem with my slicer settings. The holes are much smaller than expected, maybe an over extrusion or other parameter. The thing is that it would be a detail if I had one door, but I have printed 13 doors and eveything is wrong : doors are too wide, holes a too small. Anyway, I'll check this on my side. The curious thing is that using the same parameters I just printed a "print in place" door design having very small hinges that require good extruding settings. Thank you anyway for your design.
