Screw Gauge for M3 & M4

Screw Gauge for M3 & M4

When I'm prototyping I always seem end up with random screws that I didn't need to use or that came out of something I disassembled. I'm not great at eyeballing lengths, so I made this little gauge for M3/M4 screws. Just drop the screw into the holes to see where it bottoms out. Then put the screw into the right container. It's not really an essential tool, but I've found it useful. I included a Fusion 360 model in case anyone would like to make modifications.
