I bought 2 8x32 WS2812B Matrices and wanted to put them togehther. Ispired by https://www.thingiverse.com/thing:1903744, I first tried to change it in Sktchup, but then quickly moved tawards OpenSCAD. As I was new to it, I used https://www.thingiverse.com/thing:29211 as a starting point. The Matrix is printed in two parts (twice the same model) to fit into the Printer. In the OpenSCAD file you can change some parameters to fit your needs: // overall size of X dimension allX=188;
// overall size of Y dimension allY=174; // number of cells in X direction cellsX=16; //number of cells in Y direction cellsY=16; //cellsY=16; // grid size of X dimension gridX=160; // width of solid part of grid meshSolid=1; // thickness in Z direction thickness=5;
// thickness of the border bthickness=5; // height of z cutouts hzcout=1; // number of holes per side holesPerSide=3; //radius of holes holesRad=2; The z cutouts are preventing the grid interfering with the smd resistors.

More description and pictures with LEDs to come when it's finished.
