12 Piece Burr Puzzle BurrTools

An original variation on the classic 12-piece burr puzzle (https://www.thingiverse.com/thing:2681002). This version has 12 distinct pieces, and holds together a bit more solidly while you are assembling it. This makes it both easier to assembly in terms of manual dexterity, as well as harder to assemble intellectually in that you need to correctly position 12 different pieces.
