garden fence threaded bolt holder

I wanted to create simple garden fence.
I usually just weld recycled steel bars , but it looks ugly, requires painting if fence is expected to resist rust and so on.

So here is alternative design - it uses cheap threaded rods from hardware store, which are zinc coated and usually resist few years outside without rusting. They can also be painted or covered with linseed oil lacquer.

i've used roses i've found on thingiverse as decoration, but one can put anything on top really - i also snap example with "autodesk head" and stalin snapped on top .

provided blender file if anyone wants to create own custom holder. objects are merged togeter via boolean transform and just before export to stl just click on 'master' object (like rose) from which all transforms stem from - object will be exported with all holes OK then.

one hole should not be tapped but drilled with 5mm drill - as it's impossible to 'close' fence otherwise (or one would require left-sided thread on last holder). after putting rod there is small hole on the side to secure it with set-screw.

EDIT:
i've added openscad version.
it is much simpler, and you 'close' the fence by drilling through one hole , and just using ordinary nuts on the threaded rod to capture it.
