Thias is a more stable / durable Remix of Brad Bakers very useful original design: https://www.printables.com/model/1244644-kobra-3-max-poop-chutedeflector/files
So this remix also needs a bit longer M3 screws.
PETG is recomended instead of PLA.
The author remixed this model.
More stable / durable Version by increasing thickness at some areas and round of edges as original design didn't last long at my daily work.
