Analog Coin Calipers (Coiniper)

Project made as coursework. Meant to measure the thickness of a coin in the measurement jaws, and the deflection would be seen on the paper scale. Calibrate the scale by removing objects in the vice and adjusting the paper scale vertically along the scale until the needle points to zero. Any deflection in the vice can now be measured on the paper scale with a precision of 0.05mm!
