Modular Pixel Wall

This is a project I have had in my head for a while and finally decide to claw it out. This is a very simple print that can be made as large as you want based on how much soldering you want to do. Each section is a 4x4 chunk that has a way to align consecutive pieces. There is a second STL that acts as a final "cap" to close off the end. I use CA glue to hold the sections together which worked for me quite well.

The LED strips I used are available here: https://www.aliexpress.com/item/2036819167.html?spm

For a simple test Arduino Sketch try this, just remove the parenthesis around the pound symbol on the first three lines:


(#)include "FastLED.h"
(#)define PIN 4
(#)define NUM_LEDS 128
CRGBArray leds;
uint8_t hue[NUM_LEDS];

void setup(){
FastLED.addLeds(leds, NUM_LEDS);
for(int i = 0; i
