Template for koliva (sablon pentru coliva)

Koliva (romanian: colivă), is a dish based on boiled wheat that is used liturgically in the Eastern Orthodox Church for commemorations of the dead. Romanians decorate the koliva with crosses of cocoa, chocolate, powdered sugar or candy.
Since we had recently an unfotunate event in our family, we had to perform the memorial service, and on each Saturday we had to prepare the koliva.
I've serched a template for the decoration of the koliva with a cross symbol, and I couldn't find anything on the 3D printing sites. So, I've decided to create my own template, presented here.
I have created a 2 mm-thick template, to pour the cocoa/powdered sugar/coconut flakes etc. on top of the koliva. The template can be easily resized, to match any dimension needed.
