Hole Size Gauge 2mm to 10mm

---UPDATED: Now includes a broader range of holes --

These are gauges that help you find the perfect hole clearance when you design objects. The holes step up in 0.2mm increments; for example, the 3mm gauge goes from 3.0, 3.2, 3.4, 3.6, 3.8. You can also test if different colors or types of filament produce the same result.
