Adjustable Magnetic Spool Holder

This is one-size fits all spool holder for 3D printer filament. Magnets sit inside the little feet of each bearing block, letting you reposition them to handle pretty-much any spool size. You'll need a thin steel plate, but you might be able to make something work in your nearby e-waste pile ;)

I loved the TUSH design, so I added a few features to make it generalizable, yet sturdy enough to hold pretty much any spool.
