This is a simple macbook stand or dock made from K'nex.
Step 1: Make the big part
This is only the 2d part, with the exception of one piece. If you don't have panels, replace the 3-holed triangular panels with just a yellow/grey rod and the 35 hole ones with grey rods.
The black rod that should be as long as the blue ones (between the middle two 3-holed panels) is actually a tiny triangular panel, pointing down.
