There are many other great models for a K1 lid riser here, but I wanted a very simple and minimalistic design. 

I've included 2 models, 1 for the corners without the magnet and 1 for the corners with the magnet.

Simple to print and use. Just attach them to the existing screws on each of the 4 corners how the lid in place and then place the lid on top (see pictures).

This was printed in black “generic” PLA at 240c, 300mm/s, 100% infill. No supports are necessary if printed in the orientation show in the renders.
