DaVinci Carriage for E3D Titan Aero (Beta)

This is my attempt to create a carriage for DaVinci 1.0 which will allow installing e3d Titan Aero hotend-extruder (not vlocano) with the possibility to attach layer fan and also BLTouch auto leveling sensor. I'm still assembling it and so far it is OK, but may be I will later realize that some modifications are needed. I've included also the STL with modeled titan aero, fan duct, layer fan, and BLtouch sensor
