Updated hotend clip for Elegoo Neptune 4 Plus/Max cable chain spine by edl

Rethink of the original “hotend_clip.stl” that is one of the 5 models in “Give your Elegoo Neptune 4 Plus/Max a spine, a cable chain spine” by edl (me). This remix provides additional support for the connection point between the hot end and the chain. It now has “wings” to better handle rapid side to side motion and the weight of the spine leading to the hot end. Upgrade for both the n4plus and n4max. If installing a new chain install this hotend clip first. If upgrading remove the old clip by pulling the bottom of it forward. Work in the new clip starting with a 45 degree twist to align one wing, then the spine, and then the other wing. Push back on and it should snap in place just like the original.
