Embedded Magnet Filament Indicator Prusa Mk3

thingiverse

I got tired of gluing magnets onto my filament indicators so I decided to take a different approach. This spinner has a hollow space for embedding an 8x3mm magnet (I used <a href="https://amzn.to/2PwVLKK">these</a>). Insert a pause command just before the layer that covers the hole and drop your magnet in, then resume. If you have a Prusa Mk3 you need to insert an M600 command at the correct place in the file to trigger a filament change. You'll have to do a quick unload/load of filament and then you're in business. Once you have it printed with the magnet inside take another 8x3 magnet and clip it onto the embedded one, then take the assembly and clip it into the extruder motor. Works really well and if you do it this way you can change out spinners whenever you'd like.
