Magnetic side holder for elegoo scraper

This holder is designed to fit the elegoo scraper and affix to any ferromagnetic frame such as that for the elegoo centauri carbon (pictured). It uses three 10mm x 3mm magnets. It has the benefit of being able to fit multiple scraper blade sizes including an extended plastic blade (the standard holder did not fit my plastic blade for the scraper https://www.printables.com/model/1407561-plastic-blade-for-elegoo-cc-scraper ).

V2: changed so that the scraper can be inserted in either direction. Also, I slimmed it down to use slightly less filament. Finally, I made the magnet holes slightly smaller so that the magnets fit in snugly. I found that pushing the magnet into the holder using a flat surface like a table works best.
