I created this yarn holder for my wife because the yarn would fall on the floor and get covered in pet hair as well as getting tangled. This model is a snap together design for the two side pieces and the handle or cap screw onto the peg with reverse threads. The .3mf file is created for my Anycubic Kobra 3 Max combo with Anycubic PLA high speed filament, I have printed this with standard PLA as well, it just takes a bit longer, set your machine up for it's capabilities.
