Basic Gridfinity baseplates for Harbor Freight Yukon 20in. 3 Drawer Toolbox top and drawers split up to fit on MK3/MK4 build sheet.
I used this Gridfinity Baseplate Calculator and OpenSCAD for the top baseplate and the Fusion 360 plugin for the drawers.
I superglued the top pieces together to make one piece for stability but the drawers fit pretty well so I didn't find it necessary.
