Mod buồng nhiệt Centauri Carbon dùng nam châm 12mm

Quick and dirty remix to add 12mm x 3mm magnets that can be purchased at Home Depot.  They are ‘Magnet Source’ brand and the specific package is 07046 https://www.homedepot.com/p/Master-Magnet-0-47-in-Neodymium-Rare-Earth-Magnet-Discs-6-per-Pack-07046HD/202526367

Everything else is the same as what mrgnarvar created.  Made because people like me might be impatient and just run to a local store to grab them instead of waiting for shipping :)
