Filament Spool Adapter

I once printed a popular replacement shaft for the filament stand on the Monoprice Maker Select 3D printer but it broke and dropped a full spool onto the print. I decided that the original shaft was stronger and more dependable so I decided to make a part to fit on top of it to extend it's length. It's easy to take off and on and works well. Let me know if you like and use it.

UPDATE
I made a thicker version so the tab on the original rod doesn't protrude out of the adapter slit. It might be preferable but I kept the thinner one here too.

I did use support but may not be totally necessary.
