Portable/Pocketable Pen Holder

This is a compact pen holder for the people that carry a few pens, but not a lot of them.
It fits in a large pocket and can hold around 3 pens depending on the shape of them. It won’t be able to hold normal wooden pencils because then the case would be longer, therefore making it not very pocket-able, impossible to print on some smaller printers like mine, and raise the center of gravity leading to a higher chance of the print coming off the bed.

I recommend using supports at the bottom only for the rounded overhang for it also provides better bed adhesion. You do not need to use supports on the threads.
