Tool holders for Leapfrog Creatr (or other 40mm Aluminum profiles)

I always hate it to discover my tools have gone when I need them.
especially the small hex wrenches that I need with my Leapfrog Creatr are always just missing when I need them (not that I need them that much though...)
So I decided to make some clips to clip the tools on the aluminum profile that makes up the box of the Creatr. These are actually common 40x40mm extruder profiles with 8mm T-nut as delivered by Bosch, Maytec and othe manufacturers.

The hex wrench holder holds 1.5, 2, 2.5 and 3mm hex wrenches.

29-3-2013: new tool holders added for a pair of cutters and pliers, including a spacer just for the looks :)
