This was my exchange puzzle at IPP31 in Berlin. The goal is to assemble the three pieces into a "symmetrical shape". This puzzle can be sent assembled or unassembled, your preference. Probably more difficult unassembled, as you have to figure out what the final shape is.

Very impressive puzzle by it’s size and contrasting woods. Puzzle has littles glitches but I got the puzzle like that from the start. Nothing too visible. This puzzle was part of the 2003 IPP Puzzle Design Competition.

Beautifull puzzle. I had lot of fun with this puzzle. Puzzle has littles glitches but I got the puzzle like that from the start. Nothing too visible.

This is one of my own designs, called ChainLink... It is a 12 piece burr based on the classic 3 piece board burr.I've connected two "links" of the 3 piece board burr at right angles to form the puzzle pieces. 7 pieces of one handedness,and 5 pieces of the other handedness makes a very difficult puzzle with a unique solution.Level 7.5.3.4.4.4.3.4.3.

from billcutlerpuzzles.com:Stewart Coffin started making 6-piece burrs with pieces which did not follow the normal orthogonal rules. This restricts the number of ways that the pieces can be rotated, so limits the number of 'assemblies'. I dug up a level-7 notchable 6-piece burr design from my computer analyses which did not have a unique solution. When made with the slanted pieces, it does have a unique solution.Its hard to tell from the picture, but the pieces are indeed slanted...I'm s...

from cubicdissection.com:Tease is the first of several Cornwell puzzles I will be releasing this year. Sam uses tricky dimensions in many of his designs, by dividing the larger pieces into a much smaller common denominator. Instead of using the advantage of a smaller unit count to up the number of moves astronomically, he shows tasteful British restraint, and zings the solver with a surprising twist. Tease is moderate in difficulty, yet fun to solve and displays very well. Five...

from cubicdissection.com:Stewart Coffin's design number 54. "This is a bizarre variation of Giant Steps (Design #10), same assembled shape, in which added blocks are attached differently...Very tricky to assemble. One made in 1976."

from mrpuzzle.com.au:The puzzle is to assemble the six differently shaped pieces into this very complex interlocking burr.

The Triple Crossed Burr looks great assembled. Unfortunately, this is the unassembled version. Despite Tom Lensch being ever gracious in sending me a duplicate copy of the paper assembly solution sequence, and my multiple inept attempts, I've been unable to reassemble the puzzle. A very nice display piece upon completion. Winning bidder to please e-mail for correct paypal address. Thank you.
