This is designed to be CNC cut! BUT... you can 3D print it with either the STL file or the STEP file, STEP is better quality in all honesty however, it probably wont be strong enough to use properly so I leave it up to you. I cut these from 3mm Carbon Fibre, I have included files for 3mm and 2mm to save you the hassle of editing. I have included an image explaining which holes should be which size. I make the holes slightly smaller because you can cut them to the correct size easily, if they cut too big you cant put material back though...
