Spool holder for Joel Telling the 3D Printing Nerd's spool shelves. Designed to hang underneath the shelf, this spool holder should slip under existing spools and counter-lever against the back board. The weight of the spool will ensure there is no slipping. Encorporated a flange at the tip to keep the spool from falling off.
Designed to print with no supports with strength of part kept in mind (thick dowel portion on z axis).
May have to rotate the part so the dowel points up in your slicer. Enjoy!
EDIT: Added a "SPECIAL HIGH FIVE" Fancy Dancy version. NOTE: will need supports!!
