Large Radius Gauges - Inch

These are radius gauges for large radii - eleven gauges covering the range from 2 to 48 inches. Each edge of the gauge is either a convex or concave radius. Files for a box to hold the gauges are included.

These gauges are useful when you need to design something to fit closely to a large curved surface; at a minimum they can provide a starting point for making a test fit.

Print instructions

Print in PLA using the 3mf files provided;; otherwise :

• 100% infill
• top/bottom infill = concentric

I recommend printing in orange or yellow - makes it easier to find them on your messy bench in the shop!
