Vertical Laptop Stand

My first attempt at modelling with tinkercad. The model should be printed upside down to use the least amount of filament on supports.It can hold 5 laptops and was designed to sit on a desk worksurface. I originally designed it for 14" laptops but will easily fit bigger ones. Very thick laptops will need modification or stretching of the model. The slight angled sides stop it from falling on it's side if only one laptop is present on one side.Feedback is welcome as I want to improve!
