**If you want to support my work please download the model on Printables: https://www.printables.com/model/566277-filament-spool-holder-infinite-rail-slider/files** I am using the original filament spool holder of the “Lack v1” enclosure since five years now. For me, this is the best spool holder available. Even better than the ones with ball-bearings. It is super low friction which is perfect for flexible filaments (especially after some prints when the plastic parts smoothened themselves). But it provides just enough friction so it is not un-rolling itself. The only part which I was missing is a rail where I can position my spools freely. The original design has a fixed and a flexible part. For small spools the whole in the table then is on the edge of the spool which I didn't like. Prints without supports.
