What is it?

Drawing tool that allows you to create arcs at 5 degree increments. Marks on side are spaced at 1/8 inch increments, so you can draw slots.

Why did you make it?

I needed to make a sketch of a rotary encoder and the windows used for sensing.

What makes it special?

While there are ways to do this, as far as I know there's no compact drawing template that works exactly like this. Suited my needs well, so perhaps you'll enjoy it too!

Note that you'll receive this device with protective paper still on, and the characters will be laser-engraved, but not red. As shown in the "papered" version, the last letter may touch the radiused corner. Will probalby change that if there's a second run.

Please see the video for more about how its made, and what you can do with it!
