The Idea

A while back, I bought four Neopixel panels, each with 64 **WS2812** LEDs. I wanted to build a simple clock that would also show the temperature and display other text with special effects. I initially built the clock by duct—taping the panels together, but it only lasted a month before eventually falling apart. So, I figured a sturdier 3D printed solution would be better. I also wanted to change the layout and build a 2×2 *(16×16 LED)* square. I found many great models that would suffice, but I realised I’d have problems if I wanted to add more panels in the future.

So, I decided to take matters into my own hands, and after some revisions, I came up with this model. The panels themselves aren’t exactly square — two opposing sides are a millimetre shorter than the other two, making it an awkward rectangle. This fixes that issue and also aligns the LEDs better.

With 4 panels I was only able to create some simple shapes. I'm looking on buing some more in the future to create an even bigger display. Idea is, if I get bored with what I'm looking at, I can just unscrew a few bolts and rewire the thing to build something new!

Assembly:

**Parts required per module:** - 8x8 Neopixel panel - 2x M2 M2 self-tapping screws (5-10mm lenght) - M4 Screws (15mm lenght)

Wires can be routed through the openings in the mounts, which helps keep cable management cleaner. There’s also a bit of space above the panel near the connecting pads. I recommend adding some horizontally soldered pin headers to make rewiring easier.

I've printed these with PLA. Single mount takes < 1 hr to print (on my old Ender 3).

I’m currently a student with the ambition of becoming an engineer. I want my models to be available for anyone to build, so I’m not selling them.
