Inspired by Chris Long's gauge, I did a new design of this caliper adapters.

Place this adapter to your caliper legs for accurate distance (midpoint to midpoint) measuring between two holes or internal threads.

Its designed for professional calipers with 3.6 mm thick legs. The STL is exactly modeled with the legs dimensions, so depending on your material and printer settings, scaling will be necessary.

• Nearest distance is 8.0 mm
• biggest hole diameter is 7.5 mm (smallest 1 mm)

Printing tips

The STL is just the one for the right leg. Mirror it to become the left one. The lettering on each one is done in PrusaSlicer (use the 3mf or gcode)

I got the best results with PETG, a .25 nozzle, .15 layers, outer perimeter first and a over all scaling of 101,5 % (.3mf)
