Dollar store broom spool holder mountable/loft beds.

thingiverse

This is a spool holder that should work with most brooms from discount stores in China. Not all brooms will be compatible but I've taken a few measurements and it should work well with many options. You might need a hacksaw to get the job done, although it's also possible to make it work without one. I used a hacksaw for sure. EDIT: Just wanted to point out that even a four-reel setup like this on Amazon was forty dollars and sold out when I created this. A lot of these things are specific to niche markets - if you understand their true value, you eliminate the thousands of steps I took to develop these models. There's definitely a need for this thing. When life gives you dollar stores, mold plastic.
