I would not worry about it. As long as a flat head screw fits in the recessed hole it is fine. S drill bit turned by hand will clear out any leftover "flashing" in the hole

Dennis,
I am working on improving the ragged edge at the mounting holes. These are covered by the screws, not visible once installed. This is something that requires experimentation to correct or minimize.
These fine details (and others) are the most difficult thing to duplicate with FDM printing. These holes will never be quite as good as the original IM parts. Overall, 3D printing cannot duplicate the fine finish of an IM part, at least NOT on the caliber of machines that I have. There are some very good printers out there (costing many thousands of $$$) that can get close to IM, but they are not quite there yet for the home hobby user.
The back side is recessed. See new picture posted in album. You can see the detail and the rougher surface. Again, covered by the inner panel and mostly not visible.
These are all printed from PETG, which is a good compromise of strength, flexibility and easy to print. Different colors of the same material. The white seems to print just a bit better, that cannot be explained, since they are the same material, by the same manufacturer, using the same printer and settings. . The only difference is the color
Once I have these and other small details worked out, I will try to fit one of these to a plug in that has the corners broken off.
More to come.
