Assembly Video Story Hello there! I couldn’t find the perfect spool holder for my massive 5 kg Sunlu ABS spool, so I designed my own: adjustable, portable, and lightweight   This spool holder was made to use spare bearings from my Voron 2.4, along with easy-to-find M4 screws and nuts It’s quick to print, requires no supports, is very light, and assembly is super easy Minimum recommended spool diameter is from fi250 to 350mm (designed for 300mm Spool) There is also EXPERIMENTAL fi400 Spool Holder (left fi300, right fi400) Front fi400, back fi300 Hardware (for two sets): 4x M4 12mm SHCS Screw (can be longer) 4x M4 Nut 8x Bearings (or 4x Belt Idler) Types of Bearings Supported (ready 3D models): F604 (F600 Series) F605 F606 F607 F608 F609 F686 (F680 Series) F688 F689 F695 (F690 Series) (that's one I used) F696 F697 F698 F699 (fi400mm Spool) GT2 Idler 20T W6 B5 without T GT2 Idler 20T W10 B5 without T How to check what bearing you have? It’s simple: just measure it, check the chart below, and find your bearing’s name It’s usually better to use the biggest bearing you have. Printed pins holding the bearing can then be larger and therefore stronger If possible, use an idler bearing. They run more smoothly because they don’t create a tiny gap in the middle That’s right. you can use a belt idler instead of typical flanged bearings Here’s an example below: an idler for a 10 mm belt. Looks massive, doesn’t it? I buy idlers like this one from aliexpress here Idlers should have same dimensions like on picture, to make them work with my design: Renders
