I wanted to make a screwdriver cigar holder as a "Congratulations" gift for a friend. Resizing some of the existing models didn't work for me so I remixed a few instead. Thanks to Brendantang with http://www.thingiverse.com/thing:509880 for the top and hobinjk with http://www.thingiverse.com/thing:5308 for the bottom tip. Overall, this comes out to just over 12" long tip to tip and fits roughly a 13 cm x 3 cm cylinder inside the body of the screwdriver handle. The bottom end is a bit scary since it has those thin spires. Will take a little sanding as the tolerances aren't perfect.
