XYZ Point Scanner Using Salvaged Rotary Encoders

Having acquired quite a large number of discarded rotary optical encoders from my work place, I finally decided to do something fun/useful with them.
I’ve recently purchased a new 3D printer for my home and what could compliment it better than a 3D scanner! This project also provided me with the perfect opportunity to employ my 3D printer to manufacture the required parts.
Supplies:
- Optical encoders and corresponding optical sensors
- Arduino UNO
- optional prototyping shield
- steel-bar rails
- access to a 3D printer”
