i designed this thing in rhino. not exactly sure what its supposed to be but it has sort of a flame look to it so im going with that! this is printed in clear pet+ from madesolid. single layer in simplify 3d using the spiral vase mode. these use color changing led tea lights from here. https://www.superbrightleds.com/moreinfo/novelty-lighting/submersible-rgb-led-tea-lights-led-candle-lights-floralytes/1416/3271/ this slowly cycles from one color to the next. with a single perimeter the area just above the light itself wont print right and fall out. its supposed to be this way. if it does bridge right then just punch it out with your finger. it works best this way because there is a hole just above the light so it clearly shines through. i just uploaded a second version to this. its the same model as in the pics but has a little twist to it.
