About this project
A chunky cat-face keychain with pointed ears, cut-out eyes and nose, and a key-ring loop between the ears. Every edge is rounded, so it's comfortable in a pocket.
How it's built
- Outline - an oval head, two rounded triangle ears and the key-ring loop, blended together in 2D.
- Face - eyes, nose and the ring hole are cut out with a soft fillet so their edges are rounded too.
- Body - the 2D shape is inflated to the chosen thickness with rounded top and bottom edges.
Parameters
| Group | Slider | What it does |

Sliders guard themselves: the eyes can't cut through the side of the head and the ring hole always keeps 1.5 mm of wall.
