Instructions (please read!):
Unfortunately, I did not create the STL model in proper orientation. Therefore you have to adjust orientation in your slicer before slicing it. The face with the 5 holes should be directly placed on the printbed.
When placed this way, you won't need to any supports to print the ramp.
Magnets:
After printing you can glue in up to 5 magnets in to the prepared holes (magnet diameter 12mm, height 2mm)
See picture how the ramp is attached to the smoker.
This was tested on a pro series 22 model, but might also fit on other Traeger smokers (e.g. D2 575 or 780 etc..), where the pellet outlet has a width of 110mm.
The author marked this model as their own original creation.
