Biohazard Extruder Visualizer

thingiverse

Inspired by the various other extruder visualizers I've seen, I really wanted to have a biohazard related version. I hadn't seen one so I designed this one and it printed okay. The center is just big enough for a 6mm magnet which I understand may be a bit inaccurate but it works fine for me. Just print the design, glue a magnet with some super glue onto it (let the glue dry...) and snap it on the motor.
