Printability score
D
43/100
- →Overhang is 70° — steeper than the 45° rule. Reduce it or it needs supports.
- →Walls are 0.6mm — below the ~1.2mm minimum for a 0.4mm nozzle (3 perimeters). They'll be fragile.
- →A 35mm bridge will sag in the middle. Keep unsupported spans short.
- →A 2mm hole will shrink and clog. Holes print undersized — design them larger and drill to size.
