This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/iDzNnVg3TRY

If you want to make cookie cutter using a solid mickey stl, follow this slicing instructions. http://slic3r.org/blog/tip-printing-vases

In version v2, the wall is thick about 2mm, if you want a thin wall use version v3.

If you are looking for Mickey Mouse Cookie Cutter, it is here...want to edit? you can do it on Tinkercad. I will post the print picture soon.

Note: The wall is too thick 2mm, I think 1mm should be fine.
