This laptop stand is designed for 15" laptops and raises the back of the laptop about 7 cm. The width can be customized by using shorter or longer pieces of (aluminium) tubing. The holes are designed for a 10mm tube (I've used 10x1mm aluminium tubing). Furthermore, I've glued some tire patches on the bottom of the laptop stand, which stops it from sliding around on my desk. If you want, you can print the voronoi version (see the render).
The size of the laptop stand is just small enough to be printed on the Prusa i3 MK3(s) build plate (although I split the model, because I didn't want to risk the model warping with ASA).
