Pop-Up-Canopy Flag Pole Mount

Fts flagpoles 1.25" and smaller.
For canopy legs (or other square tube) 1.1" and smaller

The holes are meant for a bungee that hooks in and goes over the tent's canopy structure. This keeps the mount from sliding down and the hooks themselves lock the mount onto the square frame so it cannot pull out.

The flagpole tube has a hole cutout and ready for tapping for a M8 sized tightening knob if you want to clamp the flag pole into place.

Best results if you solid infill, but 10% infill is ok for single 3'x5' flag on a calm day, expect any more and ramp up infill accordingly.

Depending on if you have a moving bed and how jerky it is, you may not need supports. My Ender 3 printed this upright (rotated 90deg) with no supports, just a skirt.
