Made this to create a snowflake for Christmas display using Pixel bulbs (WS2811). Using 10 of these makes an 18" snowflake with 60 ws2811's. Using the 100mm version will make it 25" and use 45 ws2811 LEDs.
A little super glue after snapping them together will prevent it from popping apart.
I used PLA and 100% fill. So the tabs are pretty strong.
Edit: After adding 5 more parts, the distance between nodes was a bit tight so I re-scaled it less 1cm which reduces the distance between nodes of the WS2811 Pixels.
