About this 3D model

Organize your botspace with this modular set of parts to build shelving and tool holders for the TOM. (My first Thing!) There are two shelf modules here -- a closed-ended and an open-ended design, and two lengths of brackets. Pics show all of these in use. This system of parts works on the same clip principle as Thing 6951, http://www.thingiverse.com/thing:6951 but I've been working on these parts independently for a couple of months (since I first got my TOM), so it's an example of "convergent evolution" rather than derivation, I think.
