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 started 3D modeling a while back and I’m still learning a lot. 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. If you like what you see, or if you have tips to share, feel free to leave a comment. Or you can buy me a coffe!
