@Drez I use a Modus and love it. It's the size of a cigar so it packs well in a travel humidor and could double as a weapon if someone tries to mess with you lol. Here's a pic of it and second with it all apart. Nubber and draw tool all in one. If I recall they go for $40-50 and are available on Amazon.
The 3 things I would say I would like over what you've shown is 1. The double prong on the nubber keeps the cigar from spinning on the single 2. It has covers so no accidental pokes 3. It slides right in like any other cigar. It's definitely not as pretty, but it's effective.
That's my 2 cents on your project.
