Print these in black PETG with 5 perimeters. For the logo and shift pattern plates, do a color change after the 2nd layer. The holes will need to be tapped afterwards. There are intentional voids within the part, but they force perimeters to tie inside to the outside in a way much sturdier than with regular infill while still conserving material.

Print it in PETG or ABS, without supports.
