CF Tube Spacer
This is an adaptor to use carbon fibre tubes instead of the printed arms for my quadcopter design. Print these spacers along with the motor mounts found here: http://www.thingiverse.com/thing:53924.

Update 7/3/13: I have added the Sketchup file for these spacers and motor mounts for download. Enjoy!
