Update to Prusa Enclosure Spool Holder

thingiverse

Those who have experimented with the files of the Prusa i3 MK3 project on Thingiverse (https://www.thingiverse.com/thing:2864118) may have encountered stiff spool pin movement. Rather than scrapping everything in search of a more precise solution, I came up with an update that incorporates two rollers running smoothly on bearings for silky smooth motion. You can use 22x7x8 mm bearings or opt for the adapter for 16x5x8 mm bearings.\r\nThe internal fork components need to be cut away, guides inserted into external forks, and a rubber band used to join them together while keeping rollers taut.\r\n\r\nUpdate: Each roller is 90 mm long
