Extruder Motion Indicator

I was looking for an extruder motion indicator for my Creality CR10S. I saw a few of these on Thingiverse but decided to create my own design. I liked the idea of being magnetic but didn't realize my stepper motor shaft was not magnetic. So I made the adapter to slip fit onto the stepper motor and put magnets on both the indicator and adapter. The magnets used are 6mmx1.5mm that I had already. I superglued two on each part (make sure the polarities are correct before gluing in place). The CR10 was printing something else at the time so I printed this one on the 4MAX. I didn't use supports on the indicator and printed kind of fast so the print quality is not that great but it got the job done.
