Spool Holder for 638-RS Bearings

thingiverse

This is my custom design for a spool holder that utilizes 2 x 638RS bearings with an outer diameter of 28mm and an inner diameter of 8mm.\r\n\r\nIf your bearings are slightly smaller or larger, you can adjust the X-Y axis in the slicer accordingly and it will also function well with a wider range of bearings! I would say from around 28mm to 32mm it should resize and work fine using the same bolts and knots, just keep in mind the rod diameter and inner bearing diameter.\r\n\r\nMy print quality improved significantly and I couldn't believe the difference between all-plastic and actual bearings. Try it out!\r\n\r\nIf you need to purchase the bearings (638-2RS are the ones):\r\n\r\nhttps://www.aliexpress.com/item/32873079355.html?spm=a2g0o.productlist.0.0.61267e0dx3TVJi&algo_pvid=34e6abeb-e6af-43ab-a020-1365a805e599&algo_expid=34e6abeb-e6af-43ab-a020-1365a805e599-0&btsid=20ba7cfe-8c7d-4afa-b527-36f60a9cf931&ws_ab_test=searchweb0_0,searchweb201602_8,searchweb201603_55\r\n\r\nIf you need the 2 holding arms for the spool rod:\r\n\r\nhttps://www.thingiverse.com/thing:1743397\r\n\r\nIf you want a smaller filament guide:\r\n\r\nhttps://www.thingiverse.com/thing:1764285
