Pixel Icicle

I couldn't find icicles I liked to use in my lightshow, so I remixed this one. I flattened the back, added holes for five 12mm bullet node WS2811 pixels and designed mounting clips to hang them from the J-channel I have permanently mounted along my roofline.

I also made adapter shims for a 4-12 peak, both right and left hanging. The shims have an adapter clip that hold them securely to the top of each icicle, and then hang using the same mounting clips. They have alignment tabs that match up with the icicles to help hold them in place.

Icicles were designed to be printed with a 0.4mm nozzle, 0.2mm layers, 1 wall, 2 top/bottom layers and 100% infill. You can get away with less infill, but I found it didn't print much slower. The infill is only in the base where it mount. The rest of the icicle is hollow, and is only 0.8mm thick. It will print without support when printed with the point up.

The adapter shims should be printed as they appear with the same settings as the icicles.
