This puzzle applies the "bump" modification to the 1x2x3. A bump modification is when you cut off part of one side of a puzzle, then compensate for what you removed by adding that much on the opposite side. This continues until all 6 sides have been modified.
I was surprised that this actually took longer than 5 seconds to solve. Since there are no colors, trying to solve by shape causes an odd parity.
UPDATED VERSION 2: Better than the last one, includes center cap+ improved turning quality.

I used a random self-boring screw I had lying around, but the v2 has a pin as well. Stickers on the most recent version (Not the one in the video) from Oliver's Sticker Shop.
