Core Drill from Tengen Toppa Gurren Lagann
thingiverse
Here is my version of the Core Drill from the anime "Gurren Lagann". As you can see, there is some LEDs on the inside, but you don't have to add them. If you still want to add them, you should print the drill part with a 0% infill for a better rendering.
