Ultimaker Filament Reel Holder - V3

thingiverse

The reel holder, inspired by LawrenceJohnson's design, is modified to accommodate wider and smaller diameter PLA reels (92mm wide x 37mm ID). It features a smoother operation. To assemble, print two arms, one holder, and one end (0.2mm layers, 2 skins, and 5 perimeters for 20% fill in the rest and 35% in the arms). Attach the arms to the back of an Ultimaker, followed by the holder with its larger radius section fitting into notches closest to the machine's rear. Finally, place the reel on the holder and secure with the end piece in the arms' notches at the far end.
