What if your parts just fit—every single time—no matter what printer, material, or slicer settings you use?

In this video, we break down the proven design principles that eliminate the guesswork from tolerances in 3D printing. You’ll learn how to design press-fits, snap-fits, lids, and interlocking parts that are robust to shrinkage, color variation, and machine quirks. Rounded corners, chamfers, compliant features, and grip fins — we cover it all and show why designing for process is more reliable than tweaking slicer settings.

By the end, you’ll know exactly how to model your parts for perfect, repeatable fit — anywhere, anytime, on any printer.
