Screw Gauge for M3 & M4
thingiverse
When prototyping, random screws often clutter my workspace - ones I didn't need or pulled out of disassembled parts. Eyeballing lengths has never been my strong suit, so I built this small gauge for M3/M4 screws. Simply drop the screw into the holes to see where it bottoms out, then sort it into the correct container. It's not a must-have tool, but I've found it surprisingly useful. A Fusion 360 model is included in case anyone wants to make adjustments.
