1.5" Wire EDM Puzzle Cube - Zero Tolerance Stainless Steel Machining, Ultra Durable Office and Desk Accessory Gift (Zigzag Cube)

Tight fit, but after working parts back and forth for a few minutes drying the existing lube, and lubricating with a dry Teflon lube, parts fit with very little friction. They slide very easily. I’d expected the “presentation box”, I’d planned to give it away as a paperweight kept in the presentation box. Actually, it comes in a simple white paper box, wrapped in a strip of plastic wrap and a plastic bag. The machined parts are amazing in their fit and finish. I’m very happy with the purchase. I’ll probably make a hardwood “presentation” box or perhaps print one. Without the box it’ll fall apart if it is lifted from the desk unless the person knows the cube. When placed on a flat surface, the cut lines pretty much disappear so it looks like a solid cube. If placed in direct sunlight, one can see the puzzle parts outline but it is subtle. When attempting to move the parts in other directions to look for gaps or play, there is none. When moved along the cuts, the parts move easily but no play. The assembled cube has a finely brushed surface. To properly assemble the cube, the surface brushed texture should match. If it doesn’t the parts are out of place. Mine will assemble in the wrong order, a tribute to the accuracy of machining. The cube is heavy and some edges are sharp, so this is not for kids.It does measure 1.5 inches on a side accurate to within 1/64”. It does not weigh the claimed 1.2 pounds, it weighs under a pound, 0.944 pounds, or 430 grams. It’s still heavy, just not quite that heavy.Truly, I’m blown away by this cube. It is exquisite. I’ve been playing with it for 2 days now. The fit of the parts is amazing.

It was a gift to me. I shows technology that I like and understand.The tolerances are incredible, the craftsmanship is wonderful and the packaging cant be beat.It arrived on time in perfect condition.

Awesome finish almost magical

My sons and wife gave me this puzzle cube for my desk for Christmas 2024. It will be an interesting fidget item for me and is really well made. I expect it to loosen up as I oil it and use it. Tight tolerances and beautifully made. I love well machined materials and the EDM technique typically gives great results.

Scratched and damaged before shipping. Also showed up a month late.

Be extremely cautious trying to get these cubes unstuck, as the first time you open them they need to be worked in to glide smoothly. I just cut my finger down to the bone, I should've thought about how it's probably very SHARP, considering the fine machining. But other then that is pretty cool, but I can't recommend it for kids as a gift or letting them play with it.

Keep a hammer ready to put them back together. Just kidding. The machined tolerances are astonishing and I would not recommend taking them apart. Not for little hands. I used an Isopropyl alcohol pad to wipe the pieces and they moved smoothly after that. Just pulled them out partly to clean.

When I saw this cube for sale I was extremely excited to get my hands on one. Once I recieved the cube I was overwhelmed of the quality. This cube far surpasses my expectations and I would highly recommmend this to anyone. Love the product and the materials were top notch. If you are even on the fence about buying one of these cubes, just do yourself a favor and buy one. You will not regret it, trust me.
