I had left over legs from using the IKEA Lack tables in a different project, so I used them to help create a freestanding filament spool holder. It works very well and is incredibly rigid. The print is universal, so be sure to print 2 [one for right and one for left]. The hardware list is below:

You could probably manage with different size screws, or even using some type of glue instead.
Please feel free to edit this design in anyway you see fit. The Fusion 360 file is provided for easy editing.
