Summary

This is a cigar holder I use to carry different cigars with me in my backpack so they don't break. I usually smoke cigars which are in a plastic foil themselves, they all fit in well. Even the Churchill size with like 18cm fits in well.
It has holes if a short cigar stucks, could be pushed out from the back. Same from top or bottom.
You need some screws M3x25 and nuts. 3 out of the five in design would be fine. The box is sort of flexible and may extend a bit to the outside, that is ok if the cigar together with the plastic is a bit bigger, that's why I placed the screws in middle.

Shure you print both parts with the outside down.
