All I did was actually a stand for the WS2812b LEDs.
But it's more fashionable.
You can install it anywhere you want and it is completely 3d printed.
I 've installed it on my R/C car, but you can program it as a weather station or it can be an extraordinary headlights.
First of all, you need at least 33 WS2812b LEDs, but I suggest you buy some more because you may be able to damage some during welding.
Then you have to print the main part in 3d.
You should also collect wires and some conductive materials.
As a conductive material, I use the leg of a resistor or LEDs-
It's basically scrap for welding circuit boards.
Soldering iron and welding skills are necessary and the led has to be mounted on the main parts with a little force so you don't have to glue them and they don't fall off either.
To make sure the size of the hole is perfect, I made a small calibration section.
Print the calibration section first to test if the hole is tight enough.
If not, please change the zoom scale in the slicer.
I was welded in sections.
Very useful in welding fixtures.
The welding temperature should not exceed 300 °c.
At first I put the led in the right place.
Pay attention to the direction of the arrow.
Then I weld them together with lines, and then weld them together with lines.
Now you should have built the original led stick that can be used in many ways.
It depends on you.
I'm using the FastLED library for programming, which I think is the best.
