SUNLU S4 4-XTRA Spool Shell System

Meet the SUNLU S-4X MULTIPLIER The 4X multiplier parts list: 6x3mm neodymium magnets: Amazon 16mm bearings: Amazon 8mm guide rods: Amazon *If you can order the longer rods and cut them down to size they're cheaper. They need to be 8mm in diameter. 3M Scotch Weld plastic & rubber superglue: Amazon PC4-M10 fittings: Amazon *Only need 4 but I buy in bulk to keep cost down. UPDATE: If you don't intend to use the holes for the PTFE fittings here's a link for a set of plugs to install to cover the holes: PC4-M10 Plug I needed more options to dry more filament and decided to add another set of chambers on top of my sunlu s4. These are easy to use and require no modifications to your sunlu dryer unless you decide to remove the Sunlu S4 top covers. (I didn't want to do that.) These expanded covers can be used independently or together with the Sunlu
