Optimized DD Compatible Neptune 2 Hotend

I took a look at the design and decided that I wanted to make it to where it could be printed with no supports, use the original hotend mounting screws, as well as support direct drive extruders (for my case, the OMG DM1) I also decided to chop off just a bit of the vents to allow for less restricted airflow, which has proven to reduce noise, and increase cooling performance!

I would have never been able to make this original design, and I thank the original creator immensely for allowing me to edit and improve upon the design as I saw fit!

This new design should only require 2 fans to be purchased, and not require any other screws
