This is a simple laptop stand designed for Macbook Pro. Simply, it has an 18mm slot for a laptop. So anything between 15-17mm should fit nicely. You can use it to hold anything vertically that is laptop-shaped. Such as tablets, cutting boards, keyboards, paper towels, etc.

This model is designed to be rugged and strong so it is thicker than alternatives and similar models. For extreme strength, you can print it vertically.

There are 3 versions of it. Simply, I have made it too big and too wide. So, I scaled it down. Base: 184.8mm X 78.0mm X 100.0mm Thicker: 184.8mm X 98.0mm X 100.0mm Thicker&Bigger: 254mm X 98.0mm X 100.0mm

If you want a wider slot, you can cut it in Blender and fill the middle. The middle section is quite easy in geometry. If you cannot, you can ask me to do it, but no promises there.

You can scale it with simple math while maintaining most of the ratios. Only scale on the axis that is vertical to the side surface to increase thickness. You do not need to scale other axes, but you can. The original model has 18mm of span. So if you want to have a 20mm laptop, assume 21 mm span and scale 116.67%. Basically, the calculation is the desired span divided by the current span. I added a millimeter to the assumed thickness of the laptop to prevent scratching. A snug fit might damage the laptop's surface.

The reason the distance between the lowest point of the laptop and the top of the table (bottom of the model) is higher than normal is:

Well, because the rigidity is directly related to height cubed multiplied by width (h^3*b). So the higher the material, the more rigidity the structure has. If it ware too thin at the bottom connection, it would not carry the moment caused by the laptop resting on one of the sides.

Why is it thicker at the bottom? Structural stability. Pyramids are sturdy. Be like pyramids.
