Looking for something to do with extra ws2811 NeoPixel strands I had left over for Christmas and seeing the scoreboard at my son’s sportsball game gave me an idea.
After a bunch of iterations I came up with a medium-sized reflector and form to hold NeoPixels in a seven-segment LED frame in a size that would fit on my printer’s printbed (7.9 inches x 7.9 inches). The object is on Thingiverse.
Tap Plastics has an amazing magical light transmissive black acrylic that looks beautiful and dims the powerful LED light enough to make it usable. And they’ll cut it to size and ship it in a few days.

I wanted to try my hand at making a stompbox from DIY stompboxes and decided to try the Hog’s Foot, since it seemed simple and I had the parts.
What I didn’t have was a decent enclosure. So I put it in an Altoids box. It just barely fit. I wasn’t satisfied with the cutting, reaming and bending metal, so I conjured one up in OpenSCAD. I think it turned out much nicer. And now I’ve got a modifiable model to add more controls and make bigger to fit larger projects (like the Little Angel that I’ve got soldered up.)
The progression – Altoids – test box, shielding, front face, guts.
And the flip-sides.
I modeled the box after the Altoids container and gave myself some more room. I added labeling with embedded text and printed a scan of Slicey the Pig. Lots of light layers of high-gloss clear-coat and we’re ready to rock!
Some detail (preparing for the next one):
The flash and high-gloss really bring out the grain in the plastic extrusion. Perhaps I should try wet-sanding the plastic surface…
And the gut-shot.
