This little box punches well above its size. Only 120x40x50mm, it’s one of the smallest of its kind, ideal when you want proper control but don’t have room for a spaceship cockpit. Compact, tidy, and built to give you all the functionality you need without stealing your desk.

Quality Disclaimer
Every Rival product depends on the quality of your 3D prints, the accuracy of your assembly, and using the correct components. If a product fails because of poor print quality, printer issues, incorrect assembly, or the wrong parts being used, I can’t be held responsible for the results.
Design Notes
"Usually, I'll design the products by function first and will ensure it looks good afterwards. This button box was design first, function second. I wanted this to be tiny but still feature things like LED lights and a removable internal board. It was a pain, but the results hopefully speak for themselves. A great little companion."
