Ultimate Exhaust system for K1 Max for NorcoT lid riser by TonyF

I'm using 100mm PLA-printed reducers with a 150mm bathroom exhaust fan, which I purchased from my local store. It's also available on AliExpress."

Let me know if you'd like any further refinements!

You can buy 100mm fan too.

I've included both STL files for the duct connector, one facing up and one facing down.

IMPORTANT….!!!!

I recommend printing this with PETG or ABS, but I printed mine with Hyper PLA at 80% infill to ensure strength. So far, it’s holding up well

I have attached a snapshot of how I printed the object to save time and ensure a smooth print. I would recommend this method, but it's entirely up to you.

Happy Printing lads….!!!

I made this to improve the exhaust system for indoor printing with the NorcoT lid riser.

I conducted a smoke test, and it's effectively drawing all the fumes from the chamber out through the window.
