The file 'Perfect Qidi/Flashforge Spool Holder 3D Printer Model' is (stl) file type, size is 2.6MB.
I've made this spool holder for replacing the originals ones. it just required 2 bearing ball ref: 6803Z (Aliexpress or Amazon) to work perfectly. Very nice for flex filament.
Longest than the original one for 1kg Spool.
Maybe compatible with other printers. Ø of the printer's back side spool holder hole is 30mm.
Look at the JPG files for assembly. It's very easy.
Update: 10.01.2016
The spool screw have now a larger thread pitch.It's more easy to adjust.
Have fun !
