Magnetic Pen Holder Fridge

Update 130120:
Added a bigger version for more pensils.
The part between the holes on the backside is now bigger for better printing. Sometimes this part broke during printing because of the small seize.
Updated the description and pictures.

This is a small container for some pens. I attached them to my fridge.

6x10mm neodym magnets fit inside the holes.

Prints fine without support.
