Protection cover for smartphones Nomu S10 / S10 Pro. It was designed for printing with elastic filaments. If you want to use hard plastics then it is necessary to make a few slits on the side walls. The inner dimensions of the case corresponds to the phone outer size, but possibly some scaling will be needed for correction for plastic shrinkage.
Filament: TPU (thermopolyurethane)
layer 0.2 mm
raft: airgap 0.33 mm
support: buildplate (overhang angle 75°)
printing speed 20 mm/s
travel speed 40 mm/s
retract 4.5 mm at 30 mm/s
The TPU filament that I used was non-dried. So thread diameter was unstable when printing by reason of vapour exhausting. It gave some sparkling effect on the black surface, like an anthracite.
