This is a box with a mag "powered" lid to close it reasonable strong. Put gifts in it or use for stroage.
Don`t scale the box because holes also change in size.
Magnet holes are made for 6x3mm magnets. If your printer makes holes to big to hold magnets use a drop of super glue. If they are to small, scale the model bei 1% or 2% larger.
