Abloy Protec vending cylinder
When I started to put it together it was all falling apart and I had a moment of "you idiot, a cut of more than 180 degrees lets the discs fall out!" And I was pissed because this took forever to make! Fortunately, in the end, I lucked out because the rods that make up the Disc Blocking System end up holding the discs in place. So it works fine.
One more thing: there is a bit of metal that needs to be kept because it holds the spacer discs in place.
