This model is a box to support enhanced version of DIY LED controller based on WLED + ESP32.

I printed the model using PLA with both Standard and Strength OrcaSlicer settings. It worked perfectly fine. No support is needed.

Disclaimer: You probably don't know what you are dooming yourself to! Please, go ahead and buy a prebuilt controller from DrZzs shop! You will have a well-designed and fully working solution that only seems expensive.

However, if you are fine with some soldering, cutting and fitting\u2026 ;)

The project was inspired by Makers Mashup video: WLED & ESP32: The Dynamic Duo of DIY LED Projects.

This time, I added:

support for a relay that fully cuts the LED power when you switch them off. Here is a nice video that explains the reasons: Extend the life of your LED Power Supply | WLED + Relay + DigQuad.
support for IR sensor that magically works with any IR Remote control. Here is a video about such a solution: Level Up Your WLED Projects: A Guide to adding Components (no code!)
support for Logic Lever Shifter. Here is the explanatory video: Logic Level Shifter and WS2812b LEDs
2 Data lines. Here are some explanations: LED Setup: Using Multiple Data Pins + WLED Configuration. EASY Setup

The box is bigger to support additional elements.

You don't need to use glue or screws. Everything is tight enough to assemble/disassemble with bare hands.

The box includes additional fasteners to hold a relay, a IR sensor, and a logic level shifter.

There is an additional hole for the IR sensor to work.
