3D Printable Parametric “Bullet Style” LED Diffuser
Diffusers make or break LED art. I’ve wanted to play around with 3d printed diffusers as they offer not only an easy way to manufacture diffusers but also allow easy rapid prototyping iteration until the project looks just how you want. I think it’s a great application for 3d printers.
I wanted to prove out (quickly before TTITD) a basic, but tasteful, diffuser for my bike I could recognize. I’m most productive in the 11th hour and threw this together the week before I left, so some of this is a bit rough. Anyhow here’s an openscad design for a grid based diffuser for these 10mm driver in epoxy leds. Here’s how it looks from the front. This is two cubes taped together, 25 leds each. The LED strips come in 50s so this is sort of the simplest way to use all of them. Alternatively you could run a 9x9 and clip and LED, but I digress…
…here’s the back. The wiring isn’t that big of a...
