Coby designs and 3D prints a working security vault, testing whether a plastic creation can actually protect what is stored inside.

Coby takes unusual ideas suggested by viewers and turns them into real 3D designs, testing how far creativity and a 3D printer can go.

Coby designs an invention to solve a frustrating sorting problem, then prototypes and tests it to see how much time it can actually save.

Coby tests popular 3D printed products to see which ones have real money-making potential, comparing ideas, printability, usefulness, and business opportunity.

Why do so many 3D printers end up collecting dust? Coby breaks down why printers sit idle and explores practical ways to keep creating, learning, and getting real value from a 3D printer.

Coby locks himself in a room with one goal: design and build a functional product before he can leave. The challenge pushes his CAD, prototyping, and problem-solving skills.

Coby starts a 3D printing business from scratch and documents the first week, including product ideas, printing, selling, mistakes, and the first signs of progress.

Coby follows the progress of his 3D printing business and shares what finally helped it become profitable, from product choices and sales to the lessons learned along the way.

Coby tests how far AI can go in 3D design and asks whether new AI tools can actually replace the creativity and problem-solving behind traditional CAD and modeling.

Week two of Coby's 3D printing business challenge brings new products, new problems, and another attempt to turn a 3D printer into a real source of income.
