This filament holder is designed to clip on the corner of your FLUX delta printer and to hold a full sized spool of filament horizontally. It prints in 2 parts so that there aren't any overhangs or supports to worry about, and you feed the spool rod through the base "claw" to assemble it. You could glue these two pieces together, if you like.
I saw coco966's design, and read about some of the printability issues that people were having, so that inspired this 2 piece design.
Designed with DesignSpark Mechanical - RSDOC source file is included.
