Here is the duct pipe hooked up to the printer. For now I am using a piece of card for a fan guide to get the hot air into the pipe, a more permanent and proper solution will be to make a sturdier shroud out of a different material that I don't have to worry about getting too hot. The bottom side of that card averages about 140f and reaches 170f in one spot. The air leaving the projector through the pipe is about 120f and will heat the black pipe itself to around 95f. It is nice having the pipe duct as a separate unit as it transfers no vibration to the printer. I was pretty amazed at how it pretty much completely eliminated the resin smell, even during a 10 hour print.
