Aeroski Spare Spring Storage

I made this for a relative who owns an Aeroski exercise machine (skiing simulator) to store spare springs on the crossbar under the machine. You'll need to make two copies, one for each end of the spring.

I'd originally designed a set of pole storage clips, but I found that if you move the cart far enough on the tracks, the bumper stop on the bottom will hit. My apologies to the two of you who downloaded that design before I discovered the oversight. This design won't have that issue.
