thingiverse
I'm not sure if this cryptex will hold up as a reliable bike lock, but you have to take your chances when using it. To get started, just remove one part of the original O-pin, so that only one piece remains. The rest of the components follow the standard setup found at https://www.thingiverse.com/thing:2271409.
