Basic angle finder, shows a decimal angle between 0 and 25.
I created this to make the nyloc mod a bit easier than finding the angle I have to turn by hand. It has a small cutout for the hex key to fit into

Could possibly have other uses as well. Do note that it's pretty low effort so there are possibly nicer designs.

Print instructions

I printed this at 0.2 mm layer height with PLA with the default settings, generally this should not be a very hard object to print.
