This is a spool holder that should work with a dollar store broom from China. Not all brooms will work but I took a couple measurements and this should work with a lot of stuff.
You may need a hack saw but it may also work without. I used a hack saw definitely.
EDIT: Just want to point out that even a four-reel setup like this on Amazon was forty dollars and sold out when I put this together. A lot of these things are specific to niche- if you understand the true value, you eliminate the thousands of steps I took to produce these models. There was a complete need for this thing I'm definite. When life gives you dollar stores, mold plastic.
Print with skirts/brim and make sure your bed is level. I didn't use heat, but do what you gotta do.
