How to make GRILLZ at home - CAD, 3D Printing & Metal Casting

My buddy Tú asked if I fancied designing a Grill for Instagrammer Charlotte Moran. This isn't something I've ever tried before, but I do enjoy a challenge. I'm no orthodontist and certainly no jeweller, but I have a 3D printer, a basic grasp of CADwork, and a love of melting metals at home. So I decided to apply my lost resin casting approach to Grillz... what could go wrong?
