Simple Spool Holder

Simple Spool Stand Base needs Z to be at least 7 inches so the spool is not touching the bottom.

Simple spool Stand Bar needs x and y at 0.6 inches and z at 7 inches

Filament rolls real smooth and is simple to print with no support.

Tie string around the ends of the bar if you fear the spool slipping off, or print small squares to glue on the ends of the spool. (make sure squares are smaller than the diameter of the hole in the filament spool so you can replace the filament.)
