Simple Spool Holder for Acrylic Frame (Prusa i3)

I wanted a simple/strong filament spool holder for my Prusa i3. This does the trick nicely.

Print two supports.. snap a M8 or 5/16 threaded rod across the top and your good to go. I use a few 628ZZ bearings, washers and nuts to hold the spool in the center.

The M8 / 5/16 rod snaps in and out for easy spool swapping.

I also included my cable holder for giggles. It holds a 1/2" braided sleeve out of the way.
