About this 3D model

16x16 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) CHECK THE STL FILES ("DOWNLOAD STL/CAD FILES") IF YOU NEED THE UN-SPLIT (ONE PIECE) OR SOCKET-LESS FILES Instructions Print: Print the Diffuser Screen 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 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: 16x16 LED Matrix - 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 1.5A-15A (~2-5A will do for most uses) - e.g. https://aliexpress.com/item/32844702891.html or https://aliexpress.com/item/1005006126703620.html or an old USB cable (cut one end and connect the + and - to the LED matrix) LED Matrix/ESP32/WLED Assembly Guide: WLED CONFIG: LED & Hardware setup (WLED/Config/LED Preferences): IMPORTANT! - Set the appropriate Maximum PSU Current for your power supply (if powering from USB use 5-9A max – it varies with USB type and chargers.) Under Hardware Setup/LED Outputs set the correct number of LEDs in the matrix/matrices, in this case 256. This will also give you an idea of how many Amps are needed.
