Half-Mug Cookie Holder

This is a weekend project I took upon myself when a friend of mine gave me a coffee mug neatly broken in half and said "do some 3D printing stuff with it".

The design is for a mug with a diameter of about 9-10cm, I did some half-assed measurements but it worked on the first try so I hope this will work for others as well.

This might also be practical for a mug that's not broken, by using the handle to get the cookies out.
