About this 3D model

I wanted to make MikeyB's Crossfire Quadcopter but I have a Thing-O-Matic which only has a 12cm x 12cm print bed. So I sliced MikeB's arms in half and also created a smaller hub which would fit on my printer. So far so good -- perhaps not the most sturdy quad in the world, but that's what epoxy is for. Plus you can just print more pieces if you break them! :)
