The model I remixed this from looked great, but I didn't have the magnets that it required on hand. I did have 6x6 mm magnets so I redesigned it to use that type of magnet.
In order to put the magnets into the model, it does require some hammering and squeezing, but it doesn't require glue as a result.
This is my very first 3d modelling project so forgive any errors.
