Here is another object mashup created with my new PLA gear kit, this time using Landru's [Companion Cube Upgrade] as the STL object.
If you have a Replicator 1/2/2X all you need to download and print is the centre_plate, pin_plate and full_plate. They already have helper tabs, so they are ready to slice. I kept the center and pins separate so you can print them in a different colour, which I personally think looks better =)
If you have a smaller printer you can print the small_plate and plate 4 x 4 times, instead of the full_plate.
