roller bearing with cage printable

it is a proof of concept bearing with 7 rollers, maintained by a cage to keep rollers in places

Created with Autocad 123d. I provide the autocad file for editing.

I printed at 120% scale to get enough space between roller and cage.
It spins.

I added in v4 a cut in the inner cage to try to make deassembly possible but it failed.
If you have an other idea to make deassembly possible please submit.

Design is made to be easily printable without support ( and withouit infill OK )
