My original mount was a carbon fibre panorama pole and i was worried about the conductivity in storms. I wanted a little more stability so went for a 40mm pvc pipe and i have up loaded an adapter to Thingiverse should anyone want to use it…

I have not filled it with sand yet as its a first test but I can print an end cap and fill it as needs be.
It seems more stable than the carbon fibre version so far.
