That's sad... It didn’t turn out the way it should.
did it broke at the hinges?
Sometimes the slicer can’t generate one continuous line around the hinges (see the detail pics - some line breaks are OK. Breaks that happens always in the same place is not OK )
I designed for PLA but some brands can be very brittle anyway, is this the case? ( I can bend my 270º repeatedly)
I tried PETG but I couldn’t make stick to the printing bed for long,
I hope it work for you
Anyway, I just want to know if something wrong with the model so I can fix it.
