Other scrapers that have their magnets exposed have a risk of scratching the side of your printer, so I sought to make an option to completely embed the magnet. I achieved this by adding a filament change right at the height of the magnets insertion depth. To extend the pause is just disconnected my 2nd filament color in the AMS to have the printer pause on a no filament error (you could even swap your original color to the 2nd slot on your AMS to maintain the same color) I used 6 x 3mm magnets that I already use for Gridfinity projects https://a.co/d/eBLKr7X
