Beer Crate - Monetary Gift

This beer crate is intended as a monetary gift for occasions such as weddings or birthdays. It can accommodate twelve banknotes (4x3), each covered by a crown cap. I have designed the size ratios for 5€ bills, but it certainly fits any bills if you fold them correctly. Just roll the notes, place them in the crate and slide in the caps from the top.
As in the example picture, you can add other decorative models on the crate that fit the occasion (like "Just married", "Happy Birthday" and so on). You can also add models like initials to the crown caps, for example.
The example picture you see is a painted model.
