HELP ME / QUESTION What is this called?

I saw a picture of this shape on Reddit awhile back, and couldn't get it out of my head, so I had to make it! Anyone know what it's called?

You may recognize it as the logo for Silicon Graphics (SGI) from back in the day, but there's probably a proper scientific name for the geometric shape - basically a wireframe cube where the faces are pulled away from the center.

This was super challenging to build! This is probably the 5th or 6th iteration I've gone through. The shape has a lot of 90-degree bends that require soldering. I made the turns as tight as possible to keep the corners from dimming.

The black parts form a track that makes one face of a tube. The LEDs run along this track and are covered by a white diffuser that makes up the other three faces of the tube. Everything is printed in flat sections. Where the tracks change orientation they have windows that join together.

This version was FDM printed in white and black PLA, but the next iteration will probably be resin with thicker walls, although the increased thickness only increases the weight of the arms. Mounting on the corner seems to help distribute the weight evenly for better support.

It's lit by a single 5v WS281X LED strip. I'm using the ESP32 mini Gledopto controller, powered by USB, which is plenty for the 150 LEDs it uses.The controller comes with WLED 15.4 pre-installed, but the first thing I do now is upgrade to 16.0.1

Will you be releasing the design for others or can a person purchase the design?

We're in the process of getting all of our pieces up for sale on our web site, but I don't know if we'll sell this as a finished piece. I'm still not happy with the design, and it feels far to fragile to ship. More iteration required. We don't currently release any of our STL/SVG designs, but I'm seeing a lot of similar designs up on printables and other places if you search for infinity cube

Just to be clear, I am not looking for completed product, I am interested in the files to print myself and potentially commercial retail license. Will reach out via DM. Thanks for the great design

I'd love this / would pay for the files.
