Gear-shaped extruder visualizer

You can easily see movement of the X, Y, and Z axes, but extruder movement is invisible. This ornament fixes that, because it rotates with the extruder motor. Now you can easily see even tiny movements of the extruder. It is simple to attach and remove because it's held to the motor shaft with a tiny magnet. Plus, it looks super cool.

Print this and then glue the magnet to it using superglue. Let the glue dry for a minute. Then stick this ornament to the motor shaft.

Based on an idea by Peter Roodenburg.  This is not actually a remix, it's completely remodeled in Fusion 360.

Needed:

• Super Glue
• 8×3 mm rare earth magnet (neodymium magnet).
