MakerBot Replicator Tool Holder
I decided that before I lose the spare parts and allen wrenches that came with the MakerBot Replicator I would build a tool holder that attaches to the frame. It holds the 5 wrenches and includes a removable cup that you can keep small parts in. If you don't want the cup, the opening works well for putting pliers, etc in.
There are the two files, one for the rack and one for the removable cup that fits on the rack. Make sure you use rafting because the hooks on the backside are relatively narrow and tall. The picture I have on here doesn't have a couple changes I made such as a small chamfer around the holes to make it a bit easier to put them back in the rack
