Step 1: Find a Model and Import Into Tinkercad
Step 2: Drill, Baby, Drill.
When finished, save as an STL and 3D print.
Step 3: (Cooking Show Cut Here)
Now that you've got your skull, here are the rest of the bits you'll need:
RGB LED Strip - <$30 on Amazon
4 Color LED extension cable - $5 Amazon
Nut and bolt
Step 4: Solder Your Extension.
I snipped the four-pin connector from the LED strip and patched it to one end of the extension wire. Measure how long you want your lead to be and cut. Then on the other end, solder each wire to its respective color on the LED strip. The 4-pin connector has a little <- arrow on it to line up the other plug - that one is the ground. In the pix you can see that the ground is white on the plug, but black on the extension. Just remember that if it's not R(ed),G(reen) or B(lue) - it's the ground.
Step 5: Get Sticky.
- A hot glue gun is great at persuading adhesive to stick to resin-based 3D print.
- Don't put too many rings of LED strip - remember that anything on the wall of the skull is actually partially blocking the light, when v viewed from the outside. In other words, if you covered the inside wall with LED strip, the only place that light can escape is the top and bottom. We want GLOW. The strips can get pretty bright, so 2 rings will do.
Step 6: Wire Hangers.
Thread one end through the skull and tie it around a nut/bolt or any other solid thing that's bigger than the hole. Now ziptie the extension loosely to the black wire, all the way up. Loosely, meaning if you pulled the black wire taut, the extension will have a little bit of slack and not take any weight.
Step 7: Voodoo Glow Skull.
Now you can play with all the preset patterns for a soft, even transition between colors or go crazy and strobe it.
