In this segment of the InMoov robot build tutorial, the presenter explains how to finish 3D‑printed gears before assembly. He emphasizes that each gear must be cleaned and smoothed to ensure reliable motion. The process involves using diagonal cutters to trim away excess plastic, flash, and stray nubs, followed by careful sanding with an emery cloth to smooth the gear teeth. He warns not to sand away too much material, as over‑sanding can cause the gear to skip, slip, or strip. The same careful treatment applies to both small and large gears, and any residual plastic fragments must be removed to achieve a well‑formed, functional gear set.

Now, every gear you use needs to be dressed up, needs to be cleaned up, needs to be made sure that each little piece in it is smooth, separate, and well-formed. A lot of it you can do with a pair of diagonal cutters. You can trim off the extras here, little nubs and such, and little extra pieces of plastic that just Hanging off. And then you're going to need to get in there with a little— an emery cloth and sand it a bit. And you can't sand off too much or it's going to skip. It's going to slip and strip out. And that goes for the little tiny gears as well as bigger gears. All the gears need to be gone over very carefully. So Stuff like this is removed. There's little bits of plastic in here.
