BiColor Bear Extruder Visualizer

thingiverse

This is a bicolor Extruder Visualizer for the Bear Upgrade. The inlay is only two layers thick to minimize color changes, so it can be printed with manual color changes on single extruder printers that support the M600 command. See https://www.thingiverse.com/thing:3278326 for a tutorial on how to do that. The only other hardware needed is an 8x3 mm neodymium magnet which you glue to the back of the visualizer using superglue. Then stick it on the extruder motor axle and watch it turn forward and backward as filament is extruded or retracted. Here's a video of the visualizer in action: https://youtu.be/dtrZ-JVIvzo
