Spool Holder with Filiment Guide
thingiverse
This design saves space. The stock Ender 3 Pro is designed with the spool on top of the printer. But for printers like mine, which reside on Metro (TM) wire rack shelving, the most compact, space saving solution is to put the feed spool on the left, parallel to the Y axis of the printer. My design uses the original metal bracket but turned around 180 degrees. The only feed tube I need is about one inch tall and sticks straight up out out of the extruder. Also included are files for a filament guide. I've installed a Micro Swiss (TM) direct drive and all metal hot end kit, but these "things" will work just as well with original print head setup. The two roller bearings available from Amazon are 22mm OD , 8mm ID and 7mm thick. These are cheap and available on Amazon. NOTE: Credit is due to someone else for the roller mechanism with bearings (Thing # 3209211) which I did not design but utilized.. Thanks for the inspiration!
