About this 3D model
I made my own spool holder, because I did not prefered the factory flat one. 1st step: Screw out the factory top filament spool holder and push on the "Base" model onto it. I made a hole on it to get easily screw with the factory allen tools. 2nd step: After you screw back the top, slide onto the "Outside" part to the base. 3rd step: Clip on the holder ring onto it 4th step: Enyjoy :) I added a bigger diameter clip too , if you worried that the filament will fall down you could use that also. --------------------------------------- 3D PRINTING SETTINGS --------------------------------------- To print the base without any support, print it face down as the cura photo shows. 0.2 mm layer height no supports I printed in 350mm/s with the V400 without any problem.
