I have a set of 3MF files to enclose a MacroPad. They have openings for screws that go through top then PCB then into bottom, but I've been unable to figure out the dimensions of the screws needed and Google keeps trying to encourage me to design new screws, but is not returning results for determining the size and length of the screws needed.
I've tried opening the file in a number of applications (OpenSCAD, LibreCAD, etc.) and am unable to figure this out (though this could just be due to inexperience with more than changing the size of existing 3D designs).
Does anyone know if what I'm trying to do is possible, and if so, where can I read about how to do it, or if it's stunningly obvious, what size am I looking for? If it matters I'm using Linux if it matters.
The MacroPad 3MF files are found here.
