Harbor Freight "Pittsburgh" dial caliper thumb roller holder

thingiverse

This is a replacement bracket for the Pittsburgh dial caliper's thumb roller. (It also works on many other Chinese-origin dial calipers, including a no-name metric one I got on eBay from Malaysia.) There are other versions of this part available on Thingiverse that are more elegant or more faithful to the design of the original part, but I've tried instead to design a bit more strength into this one, at the expense of appearances. Since Cura does a bad job of supporting the inside of the U shape, I've included a second version of the Rev4b STL file that includes MeshMixer supports baked into the model. Print Settings Printer: DreamMaker Overlord Pro Rafts: No Supports: Yes Resolution: highest possible Infill: 100% Notes: Print it slowly, positioned horizontally, standing up with the U shape inverted on the print bed, with heavy-duty supports. Minimal postprocessing is required.
