Mario Block Box with Magnetic Lid

Designed for my Super Mario carnival costume - used as bag

There are holes in the box for magnets.
There are holes in the box for a string as a bag (I can upload a version without holes on request).
There are holes in the lid so that it can be removed. 
The question mark has to be printed 4 times and can then be glued in.

Printed with glow in the dark filament (yellow) and white for the question marks.

No support needed.
