 - draw concentric circles around it, increasing the radii by 1cm each time. you need one per sensor (3) (i made 4 because i was planning to use more sensors than i did)
 - divide the circles into 8ths
 - fill in the section like a [gray code](https://en.wikipedia.org/wiki/Gray_code#Position_encoders) (same as pictured, but skip the outermost circle)

 - glue 2 of them together with perpendicular grain directions

 - glue the third piece to the others, again with perpendicular grain to the side you stick it to
 - cut the outside into a rough circle, the same size as the encoder pattern
 - attach the patern to the plate on the side with a hole, as concentric as possible. Use masking tape to make it slightly adjustable
