About this 3D model

32x32 LED Matrix Frame No glue*, tape or screws needed Accessible USB port Wall- or desk-mounted Snap-fit sockets for ESP-WROOM-32, MAX4466 or MAX9814 microphone and DC Power Connector for easy installation Optional socket-less version (see stl files) * I suggest gluing the four front frame pieces together, and also maybe the diffuser pieces… it's getting big :) CHECK THE STL FILES ("DOWNLOAD STL/CAD FILES") IF YOU NEED THE UN-SPLIT (ONE PIECE) OR SOCKET-LESS FILES Istructions Print: 4xFront SPLIT 4xDiffuser SPLIT 1xBackTL 1xBackTR 1xBackBL 1xBackBR Print the Diffuser Screens with these settings to give the screen a horizontal “scanline” texture: Top/Bottom surface pattern: ALIGNED RECTILINEAR Internal solid infill pattern: ALIGNED RECTILINEAR Sparse infill pattern: ALIGNED RECTILINEAR Infill direction: 0 Rotate either the model or the infill direction 90° for two of the screens. If using white filament for the Diffuser Screen, printing it on a textured plate will make it scatter more light and be dimmer. Use a smooth plate for best results. A textured plate will work great for clear filament though :) For the LED matrix, you'll need: Four 8x32 or four 16x16 LED Matrices - e.g. https://aliexpress.com/item/4000544411175.html ESP-Wroom-32 - e.g. https://aliexpress.com/item/1005005972312714.html MAX4466 microphone - e.g. https://aliexpress.com/item/3256803608057399.html or MAX9814 microphone - e.g. https://aliexpress.com/item/3256805923391884.html Power Supply 5V 15~60A (~15-20A will do for most uses) - e.g. https://aliexpress.com/item/1005006126703620.html LED Matrix/ESP32/WLED Assembly Guide: I connected the matrices starting with the first one (#0, the one attached to the esp32 and power supply) in the bottom right corner (when seen from the back), like this: and then used these settings in WLED/Config/2D Configuration: If you're using 8x32 matrices or want a different setup you'll have to experiment a little with the settings. WLED CONFIG: LED & Hardware setup (WLED/Config/LED Preferences): IMPORTANT! - Set the appropriate Maximum PSU Current for your power supply. Under Hardware Setup/LED Outputs set the correct number of LEDs in the matrix/matrices, in this case 1024. This will also give you an idea of how many Amps are needed.
