I designed and printed a “replacement” case for a small camping stove (I guess it comes with a case, but I inherited one without it). I printed it in 2 pieces connected with 8 rare earth magnets, which give it a really satisfying and firm closing motion. The magnets are held in with CA glue, but were designed to sit under flush so I also coated them with a thin layer of resin and cured it for a few minutes in a nail spa.
