Project: Infinity Prism
This is a carry on to the ever famous Infinity Cube Table calculator and plans which has been extremely popular. I’ve had a number of requests for a non-cube calculator and finally got a chance to put one together. I’m calling this the Infinity Prism. Although it doesn’t have the perfectly symmetrical cube feel, it does allow for more flexibility if doing a coffee table or something that requires different dimensions.
Disclaimer: I haven’t yet built this project. Thanks very much to Tim Bergan from Virginia Beach, VA for his pictures and putting the calculator through its paces!
Calculator
The Infinity Prism can have 3 unique dimensions, the length, width and height. You’ll also need to input the square tubing size and the observable gap along the edges.
Hint: The numbers work out a lot cleaner if you adjust the Gap paremeter slightly (which is why I set to 1.415 by default). The Gap is a diagonal regional between the two nearest edges.
Cut List
The Infinity Cube had only 3 different cuts since all faces were equal. In this case we have 3 different dimensions, so we are going to have a total of 9 different length and cut combinations.
For each dimension you will need (4) of the long length and (2) of the short length. Each of the short pieces will have a slightly different miter orientation and all 4 of the long ones will be identical.
All miters are done at 45degrees. The orientation of each can be seen in the image. The numbers in brackets are the required quantities of each.
The Infinity Prism Build
If you don’t have already, I highly recommend a set of these corner magnets. You can also make up a corner jig to support them while you tack and weld everything up.
