Remix of Lucas_Rogers v2 yardstick calipers
Description
3rd refinement. Supports are needed to print the upper/internal jaws. I had best results printing this at .2mm resolution. Other settings: .4mm line width, 8 walls, 1.28mm top and bottom (an error, it should have been evenly divisible by .2). I used M3 bolts screwed directly into the plastic to hold the clamping tab on. The nut and bolt are 1/4-20. If you use a #6-32 screw that is 3" long, you can use these calipers on a workshop ruler as pictured. The moving jaw slides very well on an aluminum ruler. **Parts List** * 6-32 screw, 3" long * 6-32 nut * 6-32 wingnut * 1/4-20 bolt, with at least 3/8" (~9.5mm) of thread * 1/4-20 nut (I filed mine down to make it thinner) * 3x M3 bolts and washers. 20mm of thread on the bolts. I used a small piece of 1/8" thick (3.175mm) aluminum as a shim to prevent damage to my ruler. It also helps the bolt stick out less when used on thicker rulers. I used a similar shim made from thin ( ~1mm / .050" ) steel on a wooden yardstick. You can see the aluminum shim in one of the photos.
