This is an upgrade to the existing metal spool holder. The large size on the end means that it won't fit spools with a smaller center hole diameter. To solved that, I made this spool holder which tapers off at the front so smaller spools will fit. I also designed it so that the parts under the most force are as well supported as possible. This should be printed with support only under the tab at the back.

If you have any suggestions on how to improve the design, I'd be happy to consider them!

Happy Printing!
