dovetail puzzle for money gift

edit: the Edges are very sharp - i am working on a less sharp version

made a dovetail puzzle as a gift box for bank notes (some folding necessary)
Be aware of the sharp edges.

my printer did not like some of the edges (as shown in the pictures)
if you can give me advise to correct this - please do

printed with 0.10 - worked fine

bank notes are not included in the stl-files :)
