Hi, I'm making one but with square drills. Stores say their drills are 2.5mm but in this software you can use 2.54mm. When I do the export, should I pit 2.5 or 2.54?
That is up to you. The 2.54 will give you some wiggle room. 2.5 does not have any room for errors and you must make sure your drills are perfectly straight.
