Generic bambulabs 3d printer hotend (based for Rook printer)

I've printed a Rook 3D printer, and decided to use my spare bambulabs hotend on it. This is for a bowden setup, and as per the stock Rook design uses bed-mounted layer cooling. 

This can use either the standard bambu (5V) fan, or using the converter, the a 3010 can be attached.

NOTE: Once loaded into slicer, use the ‘split to objects’ to separate out the various components.

Supports are required.
