Model origin

The author remixed this model.

Differences of the remix compared to the original

  • adjusted size to fit Crealty Ender PLA+ Spools. (Spool hole diameter: 55mm, width: 52mm)
  • inreased the diameter of the AA battery holes to 14.5mm for better fit
  • added holes for 5mm diameter magnets (turned out one magnet in the middle hole is already enough to hold it together, no need to use 8 magnets)
  • added “creality ender” imprint to easy identification if you make these things for different spool sizes

Because of the loose fit of the AA batteries and the magnet that holds the spool weight together its super easy to attach and remove from a spool.

Tip for magnet assembly: Put the magnet on a flat screw head and the "hammer" it into the hole. Its a tight fit so the magnet stays in place. It can be additionaly secured with a bit super glue.
