So we can print in sintered stainless?
@DoubleNickels said he put a 2.50mm through hole for the bezel screw, you would need to run a 2.5mm drill bit in that hole to confirm and tap that hole to M3 x 0.5 and use the appropriate screw if you have these made with stainless.
Handy little drill tap chart, I print these out and keep them in my office and taped to the side of my tool box.
