I decided to use 1.5″ square tubing for this. It provides ~3/4″ gap which gives the design a nice compact look around the edges. You may want to leave more space between the parallel runs if you prefer a more open look. That will just mean the top/sides will be a little bit smaller for a given height. It’s still unclear whether fidget cubes or fidget spinners can help kids focus more on tasks, even though they’re marketed as helpful tools for children with ADHD. Some parents and teachers disagree with this theory and use fidget cubes as a way to keep their kids calm and engaged or as part of a therapy program to keep their kids engaged. So as I said earlier it wasn't a difficult build if you know the basics. But if you don't know then this would surely a nightmare for you and you will surely regret this. I created a couple of calculators to help you figure out your Infinity Cube cut list. The first you input the desired cube height and width as well as tubing size. The second thing you need to know is where to start now you can start from any of the sides either it's longer or the shorter side but I prefer you to start from shorter one so that it would be easy to remember. If you start from the shorter side the next two sides are going to be the longer sides. Suppose your sides are 20" and 25", so what you have to do is that start from the 20" length and then next two are the 25" long then again 20" length then next two again are 25" and so on. By doing this it's far easier for you to know about these building criteria of this table.

The first step is to figure out the dimensions you’d like. My finished steel frame sits ~19.5” tall and has a top ~17.5” x 17.5” with the intention of being an end table. Note #1: Table Height must be at least Table Width + Tubing Size used (this gives 0 gap). The Table Width is top square outer width, where I have placed the glass top. The Table Height is distance from the floor to the very top of the middle square.
