A free standing spool holder to sit on top of my lack enclosure. I had a ball bearing spool holder but found due to cheap bearings it introduced too much friction into the filament feed causing issues with my prints.
This design does the job and prints fairly quickly. The only issue i had with the original design was that the holder was not tall enough to hold the standard 1kg spools i had from both prusa and printz 3d. My solution was to add 10mm onto the height of the horizontal beam that holds the spool to lift the spool to give it clearance to spin freely. I've uploaded two STL the one with all parts includes the smaller horizontal beam as per Notkea's original design and a second stl that has just the re-designed horizontal beam with an increased height of 10mm (see pick of the two beams)
