CTC tool tray to sit on hook clip

This is a tool tray designed to sit on 2x RafaelW's hook clips. These fit on the top side rails of a CTC makerbot clone.
You'll need to print 2x http://www.thingiverse.com/thing:1242159 also.

Use tool tray 2 files to avoid the protruding hex screw which intereferes with the tray. Crude mod, but effective.
