It's basically a worn out cheapo version of a wannabe speed cube I got from a flea market for $4 LOL!
The dot holes are my own custom mod though, when fully solved the dots are in a left handed 1-6 die (singular of dice) pattern. I have previous posts on this community following my experimental journey.
Apparently I've practiced certain puzzle sequences so many times that I can reassemble a busted cube mid-puzzle and just keep going...
