Makerbot Tip Cleaner Assembly
by deherzog, published
Designed to clean the extruder tip. Basically a mount for a little wire brush and piece of a silicone spatula so you can keep the nozzle tip clean.
The TIF image has an exploded view and bill of materials.
The zip file contains the actual model parts. (Solidworks) The STL is of the base. (The only part you really have to manufacture beyond cutting up a brush and a spatula.)
