i made this with using a simple battery and led to light baby groot up.
there are 2 holes in the battery holder for the led leads to go into to make contact with the battery. the battery and its holder stay outside but led goes inside groot. i bent the wires of the led so the led bulb goes upward into groots insides.
i made mine with clear pla but white might be better or any other color would look nice.
0% infill, no supports except on the battery holder.
i use 3 in and out and top shells, tho i dont know if this makes a difference.
watch it work: https://youtu.be/sIRmeB926NA
