About this model

I didn't like how the grooves in the rubber on the bottom of the PITTSBURGH 4 in. Magnetic Parts Tray hold metal dust (see picture). So I removed the rubber cover and printed this plug to fit in the hole of the donut-shaped magnet, it fit tight but I used a bit of Shoe Goo to ensure it doesn't fall out. (see picture). Then I sprayed the magnet and plug with Rustoleum leak seal rubber (similar to Flex Seal) to give it a rubberized coating that is easier to clean metal dust and filings off. I printed this in Overture PLA with my Bambu Lab A1
