(REMIX) Quickly Measure & Sort M2, M3, M4, & M5 Metric Screws up to 50mm Long - uses nuts instead of inserts

thingiverse

This is a quick remix of Sneaks cool looking Metric screw measuring tool. The only difference is that this design uses nuts which can be heat set into the tool, instead of inserts. Otherwise it's identical. I printed and tested this tool, and it seems to work well with the nuts. To heat set these nuts, I screwed them onto a long bolt and then used a jet butane lighter to heat them up before seating them. This method has worked for me in the past and is simpler than using a soldering iron, but as always use caution since it's easy to burn things or yourself.
