Tying string to a pole can be annoying and take longer than necessary, so I designed these snap-on clips you can simply tie a string to. The clips are supposed to be permanently attached to the cover so the cover has to be tied only once.
The clip is relatively tight to prevent accidentally coming loose, but you can adjust the opening angle in the design file.
Printed in PETG for sun and weather resistance. You might need to adjust the file for filaments with different stiffness.
