External spool holder with ball bearings for FlashForge Dreamer
Description
https://www.youtube.com/watch?v=mZeiTyxmkCs Two racks firmly hold a large spool (up 200mm diameter and 80mm width) and ensure it's smooth rotation via central shaft mounted on zz809 ball bearing (22mm outer diameter, 8mm inner hole diameter, 7m width). The central shaft is assembled of a 6mm rod (pencil), 2 ball bearings, 2 bearing holders/covers, 1 central shaft spacer, a little bit of tape on the rod (pencil) and few drops of super glue to fix all the parts. The racks are put on top of the printer and secured via double sided tape, to lift the top cover of the printer via 4 corner spacers. Between the racks there's a filament guide with a hole. In order to fix the spool on the central shaft there're 2 spacers/adapters which are fixed with friction (tight hole). The uploaded STL's contain spacers which work for 1KG Bestfilament spool (200mm diameter, 70mm width, 50mm inner hole).
