150mm(D)x300mm(W)x150(H) drawer set with 2mmx2mm holes for magnets to hold multiple units together.
Magnet holes are on the top and bottom to secure this with other drawer units or paint racks that I have designed
4 x 140mm (D) x 140mm (W) x 66mm (H) drawers (Internal measurements) that fit neatly inside the main frame with finger notches to make for easy opening.
