This is a jellyfish lamp designed to have 9 RGB LEDs embedded and controlled with an Arduino Pro Mini (or ESP8266, if you want it wifi controllable)
My version was coated in epoxy to make it glassy and clear, and magnets glued to each "leg" to attach it to the body.
"body-hollow.stl" is for the LED version, "body.stl" is more for a toy.
The code is being refined at the moment, but will be posted ASAP!
