About this 3D model

Allen Keys for your 3D Printer Available in 2.5mm, 3mm, 4mm, and 5mm Granted these are more for display than functional..unless they are printed with a polycarbonate or a similiar material. Possibly 16 perimeters would work too... However I have yet to break one..specifically the 4mm key with 100% infill and Prusament PET-G. They twist. It was good CAD practice, fun, and a good filament test.
