Impossible Pyramid Passthrough Sculpture, 3D Printed Spiral Cone Toys, Pass Through Pyramid Fidget Toy, Mini Vortex Thread Illusion, Helix Screw Fidget Toy (C), Small, Orange

The pieces are very colorful and durable. They fit each other well, and it works exactly as shown. For ages 10 and up probably. A quiet way to fidget anywhere!

The video shows just dropping one piece on the other and it entwines, the one I got was very rough and you almost have to force them together. Not really good.

I bought it for my daughter. She liked it and wanted to bring it from home to work. She left it in her car for two hours and it melted.

The two cones fit together and even goes through upside down.

Not recommended for anyone who is not at least an older teen, or an adult. This is made of harder plastic, has a lot of sharp edged, and takes a little bit of patience and work to get back together.It is a cool concept, but not a great design when put together for a fidget toy.

I own a 3D printer so I know how much work can go into creating a good quality print and I'm pretty impressed by this little fidget toy. The unique shape attracted me to this item so thought I'd give it a try.I really like the two tone color that looks red-orange from one side and orange-red from the other side.The cone shape is a roughly 2 5/8 inches tall with a 1 3/4 inch wide base. Since 3D printing creates layers as it prints, there is a noise as the two parts rub against each other so this is not a silent toy. In fact it might be distracting to others if they are within earshot.Overall, it's fun to tinker with this toy as it looks interesting and behaves in unexpected ways. I would not recommend this toy for very young children as this has sharp points and 3D printed objects can fracture.

I have several of the “impossible” passthrough toys (cones, pyramids, cylinders). They all seem to be made from the same design template, so just order the cheapest one you find. They are consistently good: work smoothly, few blemishes, usually black and red/orange. This one is no exception. My kids and I enjoy them, and this one is as good as any of the smaller ones. It just comes in a stiff plastic bag, but there was no damage in shipping. The cone is the same as others I’ve gotten. They’ll make good gifts for my son’s friends.

They warn you that it is 3d printed but they don't warn you that the printing lines cause a horrible grinding sound when this is in use. It sounds and feels really, really bad. If they're going to 3d print, they need to sand and finish after.
