Bowden tube coupler

I created this to join two smaller pieces of Bowden tubing. Now it can run from my filament box directly to my printer.

If you rely on Bowden tube physics for your actual printing, I can't vouch for this, but for keeping the filament free of dust and relatively dry it works fine.

My tubing had some deformation on the ends, so it fits more snugly than I would like, but it seems to do the job. The tubes don't come apart on their own, and I just disassemble things when I want to run new filament. Works like a charm.
