Illustrator and Fusion 360

The bracer was sketched out in Illustrator and the trilobite image set so it would be etched, instead of cut.

The trilobite brooch was modeled in Fusion 360. I started off a base image of a trilobite to determine overall shape. Once I had an outline, I began building up the figure. After much trial and error, the loft tool was the most helpful application in the program. To use the loft tool, I needed to create multiple planes for the various areas of the trilobite to create a distinct head an body shape. Instead of creating rings, holes were added, for strength when holding the chain.

Prototyping

I tested the laser etching on cardboard first, to make sure the details were coming out crisp. After little success, I sought assistance through the Ideate help hours, and was able to successfully cut and etch on the leather. I started with a flat, but weak magnet and it was not strong enough to hold pins though the leather. I then moved to a stronger magnet with a larger profile, which incidentally makes it easier to grab pins from the surface. 

The 3D printing was completed on the Ultimaker. The holes for the links are currently a bit small and too close to the edge to be weight bearing. They need to be larger and inset for full functionality.
