Magnetic Nozzle Diameter Sign
thingiverse
My partner and I kept swapping nozzles and it led to us sometimes having failed prints because the other had changed it out, so I created some magnetic signs that tell us what size is currently on the printer. The signs have an internal space for a 10x2mm magnet, [Amazon link](https://www.amazon.com/gp/product/B076Y3167K/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1). I used [Prusa's ColorPrint](https://www.prusaprinters.org/color-print/) to pause the printer at 2.8mm and place the magnets into the sign and then again at 3.4mm to switch from a black filament to white.
