After trying to print the http://www.thingiverse.com/thing:36173 (Canon Tilt shift) I found out the dimensions were not correct. So I took the http://www.thingiverse.com/thing:74217 (Extention tube 50mm) and edit this into a tilt shift. It works and dimensions are correct, although it also works as an extention tube at this time.Further there's a little gap but it doesn't effect the stability of the adapter.Version 2 is smaller and has a smaller extention tube, it hasn't been printed yet!Version 3 is an edit of http://www.thingiverse.com/thing:36173 with the working dimensions
