Its a coat hanger

[Bod ...]

i 100% love the use off materials for"interesting"and other uses and a coat rail is brilliant
bbbbuuuttt just keep in mind the screws are likely to be no6 or 7 or 3.5mm in those brackets and the load will be perhaps 50-100% times the weight off pipe and water so top screw is a weak point so perhaps a drill out to 4-4.5mm and brown plug would be safer
but just my thoughts

I think the fixing went in well. But you are right.

I'll be looking at making a key holder and a toilet roll holder next.
