This cigar container allows you to carry with you in complete safety a cigar of any size (or multiple small ones), including double coronas and ones of very large rings. The container expands and contracts like a screw. Expect to have to screw it on/off a few times before the operation becomes smooth, as the tolerances are quite small.Made from scratch with SketchUp. I printed it at 0.1mm, with a simple brim. You can probably do without a brim, and certainly no support. Future work includes smoother operation with wider tolerances, deeper threads and possibly multiple widths for cigars of small ring sizes.
