Small tool rack

so i bought this set for a great price but it has some awefully space wasting storage, so in preperation for fixing my printer (which is what i bought them for) i designed a small tool rack for mounting on a wall. as i have 21 tools in the set theres 7 slots on each rack but of course you could print out more for more tools. theres is one piece to mount to the wall and then you can print and add as many racks as you want. the slots for the handles are 6mm.
