Protractor ruler for angles

cults3d

I created this protractor because the ones I have bought in any store are nos good enough. I use this ruler a lot so I designed it with my requirements, thats why every hole that represent each measure have a distance of 0.5 mm for my pencil leads to fit. Its a simple design that will challenge your 3D printers and your abilities. I added the numbers after I printed mine. After the print you might need to heat a needle and pass it through the holes.
