Parametric spool flange extender

Just a little disc to make the flange of any spool wider. Note that the existing flange MUST be removable, as this extender sits on the INSIDE of the existing flange. There is a Customizer option to make the extender touch the barrel (if the barrel and flange move together) or be spaced away from it (if the barrel rotates independently of the flange, such as a filament spool holder).

The premade model is designed to sit on the end of the default filament spool holder on the Sovol SV06. You can always measure and Customize your own, or leave a comment with the appropriate measurements and I'll upload one for your specific use case. (Since Thingiverse Customizer is somewhat broken, I recommend the excellent [OpenSCAD Playground](https://ochafik.com/openscad2/#H4sIAAAAAAAACpVVbW/bNhD+KwdmAezEimQrflNRGBmyoCiQzXGLeoPkBbR0sujQpEGe/JLU/32gZS9Jl2ItqA/E8e6557k7nJ7Ykhu+sCx6YjwlscIhp4JFzN/bkYxI73PJ1QzvcUOoMjQXNuUZazCrS5OiZVH8xJY/HJVqRajIOfvwQa9hLTIEKhBwIywJNYMqEoRN1NF2szddCweOBt7DZfAuUQeEDHH5owi
