Yet Another Samples Spool... Box

Like everyone here, I have sample filaments. There's not enough to fit on a big spool, and not enough to print a big project. And as for myself, I like to take filament from a full spool to work, so I can practice printing stuff I designed. I usually snip off a nice amount and put it in a zip-lock bag. I got tired of doing that, so I decided that the box from a small spool of filament would do the job for transport. I designed a half spool to go inside the box and a bowden tube mount for a smooth transition out of the box to the printer.

It's small, portable, and hopefully functional.
Let me know what you think. I hope others find it as useful as I do.
