What it is

A gauge to determine inner and outer radii/diameter, ranging from 1 to 15 mm in 1 mm increments.

I was triggered to design a gauge that does inner and outer fillets/radii in one piece. I wanted a wavy look and a small size, so it would still fit in a case for calipers. While I was on it, I got carried away. It looked a bit like a worm to me, so it got an eye for cuteness and as a result is carriable on a keyring.

How to print

There are three versions awaiting you:

1. with depressed digits
   • 0.4 mm nozzle or smaller is recommended
2. with raised digits
   • 0.4 mm nozzle (or smaller) is recommended since it matches the stroke width
   • 0.6 mm nozzle is possible, as can be seen in the pictures above
3. with raised digits and ring gauges
   • 0.4 mm nozzle or smaller is recommended
   • hole clearance designed is 0.1 mm

Recommended for printing is a 0.4 mm nozzle and 0.2 mm layer hight (at least for the last layer). A multicolor version is just a matter of filament changes between layers. → The provided .3mf file features modifiers for easy customization from one to three colors.

Material at one's discretion, I used PETG which is robust and has a nice flex to it.

What next

There may be improvements and modifications based on feedback given here.

Maybe, take a look at my other designs ;-)
