I really liked the Roll-up cigarette case by mbartels (https://www.thingiverse.com/thing:536620) and the Funda Clipper by Shalp (https://www.thingiverse.com/thing:1417555), so I used both files and combined them in 123D Desing to have a really useful gadget for any smoker.
Only Rolled-up cigarettes fit so don´t bother with regular ones :)
I increased the size of the cases cap by 1% to get a easier fit. The original file was a bit tight (at least on my printer).
The files are all ready, so you only need to print the clipper_and_cigarette_holder_with_cap file and you´re all set up.
Just used the "Standard" Profile for "Finder PLA" in the FlashPrint Software, easy print. It´s already correctly oriented so you only need to slice the "clipper_and_cigarette_holder_with_cap" file and press print :)
No sanding whatsoever needed, print and use :)
