About this model

Couldn't find one of the rotation indicators I liked so I made my own. Just attach a small 8x3mm magnet to the stub on the backside with superglue and it will spin as your extruder moves filament. EDIT: Also uploaded the "normal version" where the logo is facing the correct way. (I flipped it originally so it would rotate in the direction of the lines)
