When my wife and I got married, we weren’t content to buy anything and leave it as-is. We made (or had made) every component of our wedding ceremony (from the invitations to the wedding outfits to the rings). For the cake topper, we bought standard ones and then stripped them, repainted them, and turned them into partying down versions of ourselves. I’m sure if we were getting married today (that was a LONG time ago), we’d want to design and 3D-print our toppers, as Thingiverse user Erik has done here. Very cool.
