Folding hole gauge with metric and imperial measurements.
Metric goes from 20mm to 5mm.
Imperial goes from 1-inch to ΒΌ-inch.
Use supports (it hardly uses any). I tried to avoid needing them, but I didn't like any of my solutions for retention while folded.
There are STLs marked (Single Color) if you don't have multicolor capability.
The author marked this model as their own original creation.
