Minimal Under Desk Laptop Mount various sizes

Another laptop mount for under the desk.

There are a lot available, but I wanted to make my own which does not waste a lot of material while being sufficiently strong.

Most other simple mounts with 4 small brackets don't have fillets and do not look as pretty (not that anyone would see them, but I just like a good design). 
Also, I think one screw is plenty for each of the corners, I designed for a 3mm thick wood screw with 7mm wide tapered head.

Finally small brackets can be printed quickly in a strong orientation.

My print is the one with 40mm internal height with 4mm thickness, but I included files for 20-50mm and the smaller ones have also a thin version (3mm thickness).

My print profile has 4 perimeters to make it very strong for I don't trust too much in the wood filament I used for good looks.

FYI: After using it for a while, I am not so happy anymore. Using only a single screw per part make them spin a bit and I have to make sure the laptop sits perfectly to not have it fall down when inserted not straight.
