I wanted to print a new Toolhead for my Kingroon KP3S Pro V2. I settled on the mini stealthburner. I didn't want to buy a new expensive hotend, so I remixed a core that had the same spaced holes. This mod will work for any printer with a mini stealthburner.

The author remixed this model.
I made the core for the dragonfly bms have a larger opening to fit a ender 3 replacement hotend.
