Reach 3d alternate hot end carriage

This is a new hot end design for the Reach3d printer. It allows for changing parts and not having to completely disassemble the hot end carriage when you want to change things. I also tried to keep it as small as possible so that you can have part cooling and bl touch without losing any print area.

The hot end fan in the pictures was not designed by me and can be found here:
