Croydex shower rail bracket

I bought a cheap Croydex modular shower rail - the brackets seem unlikely to support the 90cm 22mm diameter rods when a curtain is fitted. So I did a quick measure up and made one in tinkercad. Surprisingly a perfect fit first time.
The central support is 85 mm long but can be cut down - my photo shows it with a 36mm central support. There is a hole all the way through to allow for screws or a split pin to be used to attach the rod.
The screw holes are not in the same position as the original
