remixed Hero Me Gen5 adapter plate for Coreception/Elf

Used the CR10 adapter to make an adapter plate to mount a stock or microswiss hotend on a sainsmart coreception 300 or Elf corexy printer.

Opened up the bottom tray to allow easier access to the the wire window on the gantry.

Added another 4010 fan shroud I mixed moves the fans forward a bit. Still not entirely happy with the fan shrouds.

Added a thick version for e3d mounting untested.
