2in1 Hotend Y Adapter "23" - Dual Extruder one Hotend (Remix)

# **UPDATE I don't know why the adapter STL was missing at all, now it's complete!

Remix - Thanks [.Solidoodle2](https://www.thingiverse.com/Solidoodle2) for the idea and good preparation.

Remixed:
=======
* Bigger Pushfitting M10
* The Bowden can be deeper lowered.
* In addition, it must be cut off at an appropriate angle.
* no hard edges, round transition guide, so that the filament glides through better


*u need only a second Extruder&Motor*
*Marlin aktivate second E (E1)
