About this 3D model

Here is a spool adapter that I designed to fit on the standard CR-10 spool holder. I wasn't 100% happy with the existing adapters so I'm trying this approach. There aren't any threads to fail or odd attachments to the aluminum extrusion. Made to fit the fatter spool versions and it has been working out great for me so far. I would recommend printing in PETG but PLA will work.
