Antenna or pole holder for a fence

This is an antenna or pole holder for a bar mesh fence (exactly for the fence post). I use a standard antenna pole (43mm) for a rain gauge. Maybe you have an other use case. I use two of this pole holder.

The object not shown in the picture is the base which stands on the earth and fits into the smaller cone of the pole. The hole is to drainage the water.

I use PETG for that with the knowledge that PETG isn't UV stable and rot-proof. But If I have to reprint that holder every 2-3 years that's OK for me.
