Fillet diameter radius gauge | Key worm

prusaprinters

What it isA gauge to determine inner and outer radii/diameter, ranging from 1 to 15 mm in 1 mm increments.For some reason victornpb's model triggered me to design a gauge that does inner and outer fillets/radii in one piece. I wanted to contain the 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 (maybe), so it got an eye for cuteness and as a result is now carriable on a keyring.How to printThere are three versions awaiting you:with depressed digits0.4 mm nozzle or smaller is recommendedwith raised digits0.4 mm nozzle (or smaller) is recommended since it matches the stroke width0.6 mm nozzle is possible, as can be seen in the pictures abovewith raised digits and ring gauges0.4 mm nozzle or smaller is recommendedhole clearance designed is 0.1 mmThe digits and lines are designed with a stroke width of 0.4 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. → In case the digits won't print neatly after said filament change: A draft shield, wipe tower or any object to consume filament beforehand (establishing good flow by doing so) may help. All versions are available with raised/depressed digits by 0.2mm and additionally 0.4mm.Material at one's discretion, I used PETG which is robust and has a nice flex to it.What nextThere may be improvements and modifications based on feedback given here.Maybe, take a look at my other designs ;-)MentionsCredits to Archimedes of Syracuse, who absolutely died for circles and Carl Friedrich Gauß.
