This is a simple way to check, with a specific filament, what diameter hole is required in designs to allow the screw to either pass through, or thread well into the plastic. The included files are all 0.1 mm difference per hole, which has been a useful resolution for my purposes.

No special considerations are needed while printing, but it's helpful to label the largest hole size with a sharpie to make the strips more reusable.

I recently decided to upload all of my designs, regardless of how likely I think it is that someone else will be looking for the same thing. I was and am still a novice at openSCAD, so the quality/customization of some of these designs is poor. If you have any specific questions, I will try to help.
