A swing canopy was constantly moved by strong winds, the original friction ones could not hold the canopy in place.
This piece keep the canopy at about 30 degrees.
It snaps onto the tubes, but I used zip-ties for stronger connection.

I sank the model into the building plate a bit, to avoid using supports. It made the smaller part even smaller, but it holds just fine.

UPD: for some reason Thingiverse did not show this model in my list, so I had to re-load it.

20250617: The original holder finally broke up, I modified it to hold the canopy at a lesser angle, may be 5-10 degrees to horizon, and printed it with PETG.
