Extruder (NEMA) motor rotation indicators

thingiverse

After discovering the concept of rotation indicators for the extruder motor, I was immediately captivated by the idea but found none of the existing designs particularly appealing. I yearned for a gear/cog design but couldn't find one that resonated with me, so I took matters into my own hands and created my own custom designs. To my surprise, creating just one turned into an entire collection of them. Each design features a raised portion where you'll need to attach an 8x3mm neodymium magnet using superglue. Once the glue has dried, simply attach it to the extruder motor and you're good to go. I initially printed only one of these designs but they all work equally well, so feel free to print any of them without worrying about compatibility issues. If you decide to give these rotation indicators a try, I'd love to see your pictures - let's share our experiences!
