Same principle that allows camber spacers to work

But one is right-handed and the other is left-handed, that's for undrilling two holes.

Terrible drill bit. Mediocre taffy puller. Adequate paint mixer.

Damnit, now I need that stl so I can make my dad's brain segfault.

Brb broke my wrist

Ok, as pictured it wouldn't work, however, if the drill ends rotated independently, the fork was fixed to the drill, and the rotation of the motor rotated both drill bits via a tiny joint inside the fork, this would be pretty neat

Oh God that took me way too long

Instructions...

1. This tool
2. Elbow grease
3. 20lbs sledgehammer

Shit, I want one for my dad just to watch his reaction

And here I thought only ai could come up with this kind of stuff

Instructions unclear.

I am in so much pain right now.

God I can't wait for the price of AI video to come down, I want to see this spin :)

Fake and staged, the holes have too much distance.
