This extruder visualizer was fun to make. It was a challenge to fit it all into a 38mm square space and make it as thin/detailed as possible. It was an extra challenge to limit myself to a .4mm nozzle. I had to slow down the print a lot to get things to stick to the build plate, my 3mf files have all of the values I used there.
