Unfortunately, it did not come with instructions. Doug is quite good at working puzzles, but this one makes a terrific sculpture, so he's hesitant to take it apart for fear of not being able to get it back together again. I tried looking it up online but could not find anything similar.
Does anyone know an official name for this thing, and preferably, where we could find the instructions for it?
EDIT 11/28/17: Doug finally found it as a Lumberjack 3D Puzzle, and here is the solution. \o/
This is the top view.
This is the front.
This is the right side.
This is the back view.
This is the left side.
I did not attempt to pick it up and photograph the bottom, as that would probably resemble the top view and I was worried about the thing falling apart on me.
