Ultralight on rail direct drive hotend carriage for BMG & e3dv6

This project is still just a concept for an ultralight on rail direct drive hotend carriage for my CoreXY 3D Printer. It will provide standard accesory adapters (fans, sensors) from https://www.thingiverse.com/chito https://www.thingiverse.com/thing:2494642 modular mount collection, so you may reuse what you have.

The goal is to create a low weigth powerful direct drive system, so the choosen NEMA 17 stepper is slim size but with the use of a Bondtech BMG extruder compensate its lower torque
