Printed on in ABS on a Kossel Clear. I left the scale at 100% and it was still big enough even with any ABS shrinkage. I think this is with 0.3mm z and speed turned up quite a bit. It didn't hurt the case, but it could have used more layers on top of the infill, which maybe would have made those solid without any infill. Only had 1.75mm filament, not the 3mm filament for the hinge pins but a couple screws worked fine.
