Quoting Eric's website: "If you like solving one six piece burrs, how about two at the same time! With a difficult level 18.6.3 solution, this puzzle is not for lightweights! Tricky and entertaining, and displays very well once solved. Three different woods used for aesthetics and also to give the solver a chance (this puzzle would be exponentially more difficult in solid wood). Ships assembled. Buyer to pay actual shipping and 4% PayPal fee.

from cubicdissection.com:Tom hits it out of the park again. This tricky little construct takes a simple yet interesting cage and seven identical pieces to create a 31 move masterpiece. There are rotations, but they won't help you. There is a lot of movement, but it wont help you. There is one and only one way to get all seven pieces in to this cage...the first six go pretty easy. The seventh takes 31 very specific, linear moves. Many times a puzzle like this can be as much a dexterity assembly a...

Great design by Derek beautifully realized by Tom in two woods which I cannot identify for you but resemble bubinga (outer cubes) and robinia (maze cube), all joints dowelled for strength and the whole thing polished so that negotiating the 3D maze is as smooth as can be. A couple of small dents in one of the outer cubes which are hardly noticeable (see pic. 3).

Very nice looking carved-animal jigsaw puzzle, not difficult but quite attractive and well-made, with each piece appearing to be hand-carved. Seven animal pieces, plus four frame pieces. The wood of the top and bottom pieces of frame have slight warpage. There's also a detachable bit of wood on the back that can act as a stand for display. I sold a similar puzzle in a prior auction.

RELEASED:11.29.2012PRODUCED:42 CopiesDESIGNER:Stewart CoffinCRAFTSMAN:Eric FullerMATERIAL:PurpleheartCOMMENTS:Designated STC #116, this Coffin puzzle was Allen Rolf's IPP29 exchange contribution. Mr. Coffin himself doesn't seem to have many records of it, stating in his book that he only made a few and had no records of ever selling any copies. I'm not sure how Allen revived the design, but I'm glad he did because this is a very interesting puzzle. Thanks to him for giving me permission to make ...

Five piece packing puzzle with a twist. As Eric so aptly described: "Blurring the line between a packing puzzle and an interlocking puzzle, the goal is construct a 3x3 cube inside the box. Tougher than you might imagine since the opening is only 2x2. The solver must figure out the proper piece orientation, as well as the order of insertion." A level 4.1.2 solution. Buyer to pay actual shipping charges. Paypal payment, add 4% for fees.

RELEASED:2.13.2013PRODUCED:40 CopiesDESIGNER:Stephane ChomineCRAFTSMAN:Eric FullerMATERIAL:Quilted Maple / BloodwoodCOMMENTS:Stephane has been coming out with a lot of new designs lately, and it was tough to pick which I liked the best. I found the geometry of the cage and internal pieces very pleasing, and the fact that Triaxe is a difficult level 24 solution didn't hurt. With only three pieces it's not impossible, but this is definitely an advanced puzzle. Lots of movement and lots of dead end...
