I needed form fit organizer trays to keep my growing assortment of cricut maker 4 tools organized in my toolbox. this file contains trays for the thin, standard, and deep cutting tools as well as the knife cutter and the quick swap tool body along with 9 holes for the quick swap tools. I found gridfinity AFTER i had already cad'ed the files out. but could be easily adapted to fit the gridfinity system if you already have that in the drawer. hope you like them.
