That’s a fantastic design, @Willem.
It’s a product line I offer so I’m looking for a solution. I have some base shapes (rings, pendants, etc.) you can customize. Originally I thought they’d all be handwritten, but most customers opt for a font.
Also, I take them into 3DCoat to soften and boolean the designs. The hard edges of extruded curves do not cast well and 3DCoat is super simple to smooth, boolean, and produce a clean mesh for printing.
Today I’m adding a new shape (mobius strip) and making one for my daughter as a pre-k graduation present. I played Willie Nelson’s Valentine for her and now she loves “Willie Welson and my favorite part is when he says ‘introduce your heart to mine’ because it sounds like our hearts are going to play together.”
