Gridfinity spool holder

this is my Gridfinity compatible spool holder. it is designed to hold 4 6x2mm magnets in the corners i was inspired byhttps://makerworld.com/en/@LeviMoore and his Gridfinity designs with magnets. i don't have print pictures as this was simply a design job for a friend and i don't currently use the system. it is a 1x1 tile
