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.not printed myself yet, but just print one of the mount pieces and as many of the racks as you need. maybe a bit of silicone oil to make the joint a bit smoother, but there is a small gap between the connection which should be enough. ive tried them in cura and they seem to work properly and load but please let me know if any problems arise
