About this 3D model

There's been a few tool-holders posted, but they never fit my set of tools. So I thought, why not make a modular tool rack that hangs off the side of the Cupcake and that people can customize.There are two basic pieces -- "lip" and "nolip". The nolip pieces are for lighter objects and fit next the the z-axis parts and rely upon the lip pieces for support. The lip pieces are for heavier parts and clip onto the side of the makerbot.Due to the space between the z-bolts not being a multiple of the z-bolt mounts, there will be a small gap. If this really, really bothers you, stretch out one of your lip pieces to take up the slack.
