Hemera Fan Shroud and BLTouch holder

I put an enclosure around my MP3DPv4 with a door on the front. The stock fan shroud stuck out to far and would hit the back of the door.

I flattened the parts cooling fan in this remix. It gave me the extra ~5mm clearance I needed to keep from hitting the door.

It does make the fan closer to the BLTouch, but I haven't noticed any issues from that.
