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.

Thanks! I wondered about the glue stick trick, but I think you're right that a taper would be better. I have to wonder why he didn't say that, but maybe he was tight on time or some other thing.

YouTube has video nerds. There are very few advanced Makers on YT. People like Ben from Applied Science are on the short list. I tried making content for YT a few times but that is like a full time job. YT stopped promoting real low level Makers and community stuff around 2017. Prior to that I had something like 1k5 people I followed on there. When they got integrated into ISP with local caching they had to limit what people watched by promoting a much smaller slice. The result is that now advanced content is not promoted well. YT only wants people that can churn regular garbage like cable TV all over again. So he probably didn't even know. Still his niche is in transferrable design for a farm and that can be interesting.
