CubixLED - an LED matrix frame project

thingiverse

I've designed this project for a large-scale RGB 8x8 matrix project. Smaller 4x4 versions are also included for other printers. Two versions of each size have been created - one for 5mm round LEDs and another for 5050 style square LEDs found on flexible strips. This setup will be used with some individually addressable RGB LED strips, specifically the Digital Dream variants found on Amazon that have been cut down and mounted on the back. Some frosted lighting film, Roscolux 116, will be attached to the front using VHB double-sided tape. Considering the strips cost around $12 per meter, I can build each matrix for about $20, which is significantly cheaper than comparable 8x8 matrix panels. A Teensy 3.1 controller will likely be used, since the strips are designed to be connected end-to-end, allowing control of multiple panels with one device. Photos will be added as the project progresses. Single cell and 8x8 SCAD files have been created. First-time user of OpenSCAD so creator beware! UPDATE: A new version has been added that matches most 60 LEDs per meter strips (16.667mm apart). This requires less cutting and soldering, reducing thickness to 12.7mm. Strips can be secured directly to the back, enabling edge-to-edge matrix displays with 8 running strips.
