Dual hobbed bolt extruder V2

The first design of the dual hobbed bolt extruder was "working" but it has some problems.
In the (little) free time I have I was keeping working on it.
This is the second version.
More linear and "compact".

yeah I know it's not so compact as I want... but I design this to work with my big core xy as a bowden extruder so it's ok if it's not so small.

it should work fine even at high speed.

Still WIP. I haven't print it yet.
As soon as I can I'll upload the single stl
