Fillet diameter radius gauge | Workshop coaster

What it is

A compact gauge to determine inner and outer radii/diameter, ranging from 1 to 20 mm. It also works well as a coaster.

What to print

There are multiple variants awaiting you:

	central gauge version 1 measures from 1 to 10 mm in 0.5 mm increments ring gauges for round stock, drills, … from 1 to 10 mm in 1 mm increments, clearance designed is 0.1 mm
	central gauge version 2 measures from 1 to 10 mm in 0.5 mm increments central hole (35mm) digits running cw/ccw like on the embracing gauge
	central gauge version 3 measures from 1 to 10 mm in 0.5 mm increments central hole (26mm) bigger depressed digits & coloured edges
	embracing gauge version 1 measures from 11 to 20 mm diameter in 1 mm increments 15° angular scale
	embracing gauge version 2 measures from 11 to 20 mm diameter in 1 mm increments 15° angular scale huge depressed digits & coloured edges snap fit with central gauges
	stand alone versions equivalent in radii/diameter measuring function 5mm thick not interlocking no angular scale
	Christmas edition (once contest related) Since it is around that time: Have you ever considered hanging useful or edible things as holiday decoration, that could be kept by the attendees? Nearly every year my grandma told me that this was exactly what they did when she was young. → This design is round, has at least one hole and to a blind eye it may resemble a snowflake. Print in colors that suit the purpose or taste of the future owner, combine it with a nice ribbon and voilà; decoration.
	Recommendable remixes If you want this design expanded to measure up to 40mm (or as coaster for a beer-keg?) DavidsGotWood got you covered here with a next size up embracing gauge.

How to print

Except for the versions with bigger numbers, the digits and lines are designed with a stroke width of 0.41 mm. Recommended for printing them is a 0.4 mm nozzle and 0.2 mm layer height. Printing with a 0.6mm nozzle and Arachne activated in PrusaSlicer is possible, as can be seen in the pictures above.

A multi color version is just a matter of simple filament changes between layers. The digits on top differ in height by 0.2 mm which lets you print them in two colors. → The here orange depicted digits read the adjacent bulge diameter and are 0.2mm higher than the white ones, which read the adjacent inside curvature.

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.

Material at one's discretion, I used PETG in four different colors.

What next

There may be improvements and modifications based on feedback given here. The current font used is OCR-B. The quest for the best printable fonts is not over, just further elaborated here.

If you do prefer a radius/diameter measuring tool that is even smaller and can be carried on a keyring, consider printing my radii worm or diameter chain. Measuring instead of gauging angles can be done with my printable vernier bevel protractor. And efficient identification of metric nuts & bolts can be done with my cylindrical screw measuring tool.
