UPDATE!!! Cigarette Box V2, ...automatic opening

UPDATE!!!
I've reworked the box again. It's now even more stable and the locking mechanism works better too! ;)

Hello friends,
I was just annoyed that my cigarette box was always getting crushed.
So I decided to construct a more stable cigarette box!
Here are two boxes. One for 19 cigarettes and one for 40 cigarettes (BigBox).

 

And with a little magic, the box opens automatically with a little pressure.
If you like it, I would be very happy about a LIKE or a boost!

PS:The holes for the spring are now present twice on the upper and lower parts. You have to select the holes depending on which way the spring runs.
