A Cheap and Easy Way to Make Your Own Infinity Cube
Thomas Jensma shares a simple(ish) technique for constructing an infinity cube with a single-piece 3D-printed frame.
Infinity mirrors, and their extra-dimensional cousins, infinity cubes, use a series of mirrors to bounce light inside back and forth — apparently into infinity. While there’s a good chance you’ve heard of them, and perhaps have some understanding of how they work, what's the easiest way to actually build one? For one excellent idea, be sure to check out Thomas Jensma's latest project.
Jensma's device uses an external Arduino-style board for control, along with a 10A or 5A, 5V supply to provide power. It houses 144 LEDs inside, which conveniently works out to exactly a meter. The frame is 3D-printed at an angle, so that in theory it can be printed in one piece without supports. This all-in-one design means that the mirrors facing each other will be quite parallel to each other, providing a “more infinite” experience than you’d normally be able to get without a lot of adjustment. Mirrored surfaces are made out of six plexiglass squares coated with mirrored film.
Because of its simple design, Jensma was able to put this cube together in a day, at a cost of around $25. Likely the longest part of the build was the 10 hours required to actually print the frame. So if you want a “same day” cube, you’ll need to get started in the AM, or prepare to stay up a bit!
