I saw the E3D Nozzle holder, and have been using it for a few months until I built my LACK enclosure. I wanted something to hold my nozzles, and preferably hold it near or next to the enclosure. So I threw the STL in tinkercad and made a whole tool caddy around it, except this time made it work for all of my tools.
It is designed to hold the following:
1) Build Tak Spatula
3) wire brush
5) wire cutters
6) a nozzle tool I made myself from a 7mm driver with an M4 nut superglued into the socket and the driver (handle is here https://www.thingiverse.com/thing:137367)
7) Prusa heating block tool (https://www.thingiverse.com/thing:3441470)

You will need some screws:
For the side: 2 x #14 x 2"
For the bottom: #6 x 3/4"
For the locking bar: 2 x M3 screws that are small
