BIQU H2 Extruder Front Mount 5015 Fan Duct

Remix of eight_heads BX version https://www.thingiverse.com/thing:4682915/files. This was done primarily for the Ender 5 Pro but will fit any BIQU H2 installation. This version gives 360 degrees of cooling. I've also remixed the mount so that its slotted for height adjustment and also off-set from the hot end so the heater cable can run up the front of the extruder. This also allows better airflow for the extruder cooling fan. I've also included a spacer/gap adjuster (2mm) which can be placed under the fan duct to help support and set the gap and keep it parallel to the bed while making the final adjustments and tightening of screws. Carefully use terminal commends to raise the bed until Z0 position is reached with the spacer in position, then nip the screws on the mount, fit the fan and tighten. Finish by lowering the bed and removing the spacer. Print in PETG as a minimum due to closeness to the heater block.
