Explore the capabilities of 3D printing with the Impossible Fidget Cube! This 30 mm cube features a sphere "trapped" inside, offering both a visually stunning and fun-to-play-with design. Available in single-color or dual-color variations, the cube requires minimal supports and can be scaled to your preference. Perfect as a desk toy, fidget tool, or to simply showcase the magic of 3D printing.

Use tree supports.

Special thanks to JUSTWAY for making this project possible!

I’m incredibly grateful to JUSTWAY for supporting this project and helping turn my idea into reality.

JUSTWAY is a professional manufacturing platform that offers everything from 3D printing and CNC machining, to injection molding and urethane casting. In this case, I used their 3D printing service—and I was truly impressed with how easy and smooth the entire process was.

Their online system is super intuitive: just upload your model, choose the technology and material, and they handle the rest. No back-and-forth emails, no hidden steps—just a streamlined, worry-free path from design to delivery.

What stood out to me most—aside from the print quality—was their fast and helpful customer support, which made the whole experience even better.

Whether you’re working on functional parts, prototypes, or simply want to try something that goes beyond your home printer, JUSTWAY has you covered. They support a wide range of technologies including FDM, SLA, SLS, SLM, DLP, PolyJet, and more—with materials ranging from plastics to metals.

If you’re thinking about outsourcing your next complex or high-precision print, I highly recommend giving JUSTWAY a try!
