Overture, Elegoo, and Polymaker Spool Adapter

Remixed Jarhead's excellent spool adapter for 200mm cardboard spools like Elegoo, Overture, and Polymaker (note; this SHOULD fit a Polymaker spool, but I don't have a test spool here. If someone could test it out for me that would be great!).

I made a few changes for my own personal tastes;

• Dropped it to 3 spokes
• Added lettering for easy ID
• Added grip to the outside edge to improve feeding from AMS
• Resized ever so slightly

If you need a spool for a different size, I highly recommend checking out Jarhead's model. It's parametric and you can size one up to whatever you need.
