I cut this fan cover from some scrap aluminium at bitraf today, used a 2mm singleflute @ 6mm feedrate and 1,4mm cut depth.
The screwholes got a bit damaged in the process of holding down the part for the cutout. it did not matter, as they will be hidden when the part is screwed on.
Othervise, i´m happy with the part, and so where the client!
