NEW DESIGN PART 6

In this episode, we take the outsole pattern from the last video and turn it into a clean, solid, production-ready geometry inside Rhino.
I removed the elements that were too bendy or didn’t touch the ground, and now we rebuild everything properly—solid offsets, clean intersections, SubD → NURBS conversions, boolean unions, edge checks, and manual adjustments so the piece is airtight.

This is the part nobody shows on YouTube:
the real cleanup, the real decisions, the real hand-finishing that turns a cool concept into something that can actually be manufactured.

We talk about:

When to offset in Rhino vs. Modo

How much thickness makes sense for printing

Why undercuts matter for injection molding

How to manually align and rotate pieces that won’t behave

How to union everything into one clean watertight part

Why “good enough” is often better than wasting hours on perfection

How this outsole becomes printable, paintable, and ready for prototyping

Whether you’re building slides, sandals, clogs, or experimental footwear—this video shows you how pros actually prepare complex details so they print and fit right the first time.
