Kobra 2 Neo Top-Mount Spool Holder

This model reuses the 'core' part of the provided spool holder to convert the Anycubic Kobra 2 Neo to a top-mount design. My design is based on several others I've seen on this site and some of the others across the internet. It mounts to the injection molded top piece of the Kobra 2 Neo with two 10 mm M4 bolts. 

This model was designed with OnShape, and the CAD files are available if you make an OnShape account here.
