The wheel to set the height of the showerhead was broken (just after only 30 years!) and replacement was nowhere to be found. With the help of my Ultimaker I was able to repair it by printing a bolt and thread so we can tighter it again.
Made a laser engraver from 2 old DVD players. (not my own design though).
Used a plastic ball to create a big trackball.
Used special touchfoil to build a touchscreen on a glass panel.
Used an arduino and a proximity sensor to build a warning system for our tube-mail system.
