Brain Teaser Puzzle with Stand

This is a replica of a puzzle I found here
http://www.craftypuzzles.com/wooden_puzzles.html

The first version I printed the tolerances were to tight.

I loosened the tolerances up some in this version.

15 total pieces for the puzzle, 1 extra with the stand
Qty 1 : Piece 1
Qty 1 : Piece 2
Qty 3 : Piece 3
Qty 2 : Piece 4
Qty 8 : Piece 5
Qty 1 : Base (optional piece but does make it easier to assemble)

Print the pieces with 'Flat' in their name.
I oriented them for printing.
