Metric screw measuring device - M2/2.5/3/4/5 4-50mm

**This is now available in my Etsy store, along with a larger version covering larger screws: [https://cmhprinteddesigns.etsy.com/](https://cmhprinteddesigns.etsy.com/)**

**Update 27 Oct 2020:** I made an edit to this thing to add a small change with screw threads in the back, and when I saved the edits, the thing somehow became visible only to me, showing a 404 for everyone else.

I have printed several of that one, but realized that I wanted to have threads in my design as well. There's just enough room in the back - maybe not for press-fit nuts, but I can do printed-in threads. I've printed off the new one (see the silver print in the photos) and it works well. I did chase all of the threads with my metric tap set, but they didn't require too much cleanup after printing at 0.2mm. The originals without the threaded holes are still there as well.

Quickly sort and measure metric screws and bolts in sizes ranging from M2, M2.5, M3, M4, or M5 with lengths from 4mm to 50mm. Screw diameter sizing is a simple go/no-go clearance check which is faster than threading in a screw. Note that this…
