Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4728109. Remixed these from a few other designs will give a mention if and when I find the originals. I havent been able to test fit yet as I'm still waiting on my extruder comming. I used the sizes from the drawing on their website. This is still a work in progress and will update as I go along. For the Ender 3 pro. Changed to V2 Duct, added fins to allow air flow.
