Lenovo Legion Pro risers

Lenovo recommends against using cooling pads and instead recommends lifting the laptop up in the back by about a centimeter.

These do just that. Print two, one for each side. Not sure how many models this fits, but it slots onto the OEM rubber foot in the back. Room for 4x 8mm diameter rubber feet on each one. Small enough to throw them in my bag for gaming on work trips.
