Tips on printing
- The cap is divided into two parts: the "cup" and the bearing post. The bearing post should be aligned at the center and the bottom should overlap with the cup. See cross section above.
- Scale the cup's and the bearing post's sizes individually in x and y for perfect fitting.
- The bearing post should be solid at 100% infill to ensure sufficient adhesion onto the cup. Adjust settings of the cup by preference.
- Add support along the outer edge of the cup.
