After searching online for a spool storage solution, I eventually decided to make my own exactly how I want. All of the hangers I could find online either went through the middle of the spool (so you can't vacuum seal) or could not be hung from wire shelving.

This spool hanger is designed to hang from the ClosetMaid wire shelving system. The pipe holes fit a 1" pvc pipe that I bought online.

I printed it in Bambu Basic PLA and as you can see it is very strong. My pipes are 40" long. I recommend spacing the hangers at no more than 36". The dovetail is a tight fit, but does not require any post processing.

Let me know if you have any questions or would like me to modify it to fit your needs. I also added a screw hole at the bottom of each pipe hole to allow you to insert an M3 screw. Not necessary, but allows you to keep the pipe tight.
