Need to build a custom rotary encoder wheel for that precision motion device you are making? Well, Nick Ames has you covered with his encoder wheel generator script.

What would you want this for, you ask? Well, a rotary encoder is a device that uses a fixed-position sensor (in this case an optical one) that measures a series of markings to determine the speed, position and direction that a part is spinning in. By using a generator like this one to print a custom pattern, you can create one that works well for the application that you want to use it for.
