Kobra 3 Triple Air Duct Remix - To fit the OEM hot end instead of ceramic.

I wanted to be able to use the triple duct design but don't have the ceramic hotend its originally designed for. I cobbled together a version that's relieved with enough space to accommodate the factory heat block. Original designer recommends PETG, ASA, or ABS and I would also but I have printed a few in PLA during testing and they held up fine for me but you should keep an eye on it between prints if you try it out.
