Canon EF Lens adapter for Raspberry Pi

Make your pi camera super-telescope with Canon EF lens.......
For people did not have accessible 3D printer, another model in shapesway (http://shpws.me/Hz4u) should do the same trick.

update for The new 8MP V2.1 camera.
The picam_ef_adapter_v2.1.stl should work on both old (5MP) and new (8MP) camera modules.
