This is the bottom piece of an Instant Pot IP-DUO60 v2 but may fit other units. It replaces a melted bottom as a result of putting the Instant Pot on a hot burner.

I suggest using PETG for the material and using at least 6 perimeters so that the offset air hole covers can be printed without support. At 40 mm/s requires about 6 hours to print and it uses about 20 meters of filament.

Included is the scad file if you want to make changes, as well as the stl file that I used.
