About this 3D model
This is inspired by Bluelinegecko's tool holder. http://www.thingiverse.com/thing:406938 I deigned this rack to match my Skewer Holders curves http://www.thingiverse.com/thing:430119 I also included a place to put a 5.5mm wrench to tighten the bed leveling lock nuts, you can find the wrench I based the size off of here. http://www.thingiverse.com/thing:130949 This tool holder fits tight, I found the best way to install it was to hold your breath and put it on fast so it does not break.
