The Nine Puzzle.

Golly.... Boys and Girls, I haven't posted a puzzle this meridiem... so as the carpe diem's desire to make it meri, here is another installment.

     

This is a 9 piece “dissection” puzzle, which may give an just a hint  to its name.

 

As usual, the greater the number of pieces, the greater the DOD (Degree Of Difficulty). 

 

This puzzle only boasts 2 solution options, however, the star makes for a novel new shape from the others I’ve posted.

 

It was produced in two sizes,

1.     90mm x 79mm

2.     56mm x 49mm

There is no real significance to the sizes other than the small one was approximately ½ the size of the bigger one.   The size of the frame was based on the original size of the puzzle in Sketchup with the frame sized to accept both solutions and enough of a border around the puzzle.

 

Both the large and small puzzles were sanded (in the solution setup) 

to remove the laser burn marks,

 

Used compressed air to blow out the sawdust,

and learnt the hard way to prevent the small pieces from becoming uncontrolled missiles,

 

The large puzzles were buffed using the Beall Buffing system, while the small puzzles’ pieces were too small to buff without spending hours on all fours trying to recover airborne pieces.

  

Then it was time to package each puzzle,

  

If the puzzle is made “manually” the sizes could be difficult from measurements directly available from my models, however, if lasered/CNCd or 3D printed, there should be no issues other than your size choice as long as it is changed in a common ratio. 

 

Although it is not officially recognised as a Tangram, I could see potential for different shapes with the 9 pieces.

 

For anyone interested, the SketchUp model is available from the 3DW at,

the A4 PDF solution and/or the SVG file (without my boof head). The SVG is of the small size puzzle, but being an SVG, it can be resised without issues with software like the free Inkscape or other SVG editing software… you may wish to change the font from “BRUSHED” to your preference.

 

Anyone interested in my puzzles (or other authors’), you can see them all here in my “Puzzle Collection” .

If interested in any of mine (LBD), measurements can be made available on request for anyone not familiar with SketchUp… though a working knowledge of SketchUp’s navigation (as opposed to its design/use features) and access to 3DW could be of benefit.

Christmas is coming and puzzles make a great stocking stuffer... for all ages.  
Kids love ‘em and most of us are still kids.
