Just a quick remix tof the Feet_Riser_35_Lightweight_B file from the original set. This has one edge of the foot in line with the extrusion to allow for a different motherboard cover to fit and for the psu cover to fit well.
One side sticks out a little bit more than the other.
Fit with the sticking out section outwards.
