Chimney Cowl

[Onoff]

I need a couple of vented chimney cowls. Pot is 14" diameter. Any suggestions as to where, local roofing place ones are too small a diameter.

The printer will only print 256x256x256mm. Don't think I haven't thought of it.

 

Mulling on printing 4, slip together quadrants that I could form cement over.

Are these working chimneys?

 

Why do you want cowls?   Rain and bird guards or spinning ones?

For the former, I googled and found 250mm easily,  

 I suspect you may need to reduce the diameter to suit the biggest you can readily find. It might look odd and not keep the rain out unless modified.

 

OR the non-mechanical ones look very simple and could be modified at hood and the legs, or fabricated even.

Non working chimneys. Also considering making something like this:
