I was struggling to get a nice spray holder for my wall. The model that mathiasl published came close, but I saw no need for bolts and nuts.
So this one is with the HSW connector attached.
I ended up remodeling the whole thing, but it's still based on mentioned model.
I added my print file for the 65mm version, which has organic supports. for the connector bottom.
Added a 68mm version by request.
The author remixed this model.
Removed the need for screws; has a full HSW plug
