Machine Screw Reference

thingiverse

I wanted a way to check the thread of weird bolts and threaded holes in my junk drawer so instead of buying calipers I am over-engineering this solution by literally making threaded dummy screws. I will add the other common screw sizes but if you want to do it yourself I added the files to do it in freecad. Screw size is etched into the bottom. --- Update: after 24 hours I decided my original design is dumb and I made a new one with a key ring spot.
