Handy Measurement Jigs
When I’ve got free time, I love to play around with 3D printing, my HobbyCNC DIY Router and electronics. There is that point in the design where the schematic (or drawing) needs to turn into a real, physical product, and, like most hobbyists/makers, I’ve got a collection of parts that aren’t always well organized, or some part I need to match or duplicate. So I made a couple of quick-and-dirty measurement tools that work great for me!
It’s never clear to me if that machine screw is an M4 or a 8-32, an M3 or a 4-40.
Super simple design, simple assembly, small and handy. 2″ x 1/8″ x 8.6″.
