This is an adjustable laptop stand, it can be adjusted from 0 to 22mm, so you can pretty much put any modern laptop into it. It takes around 200g of filament to print, and there is no additional hardware requied. There are a lot of tolerances built into the modell, so no need to scale anything up or down.

For the two big parts I recommend printing at least out of petg, since it can be hot around a laptop, and I strongly recommend using brims and gyroid infill and 0.28 layer heights with a 0.4 nozzle.

For the screws I recommend bumping the layer lines down to 0.2.

For the TPU inserts i recommend 100% infill and just glueing them to the other parts with superglue.
