This is a design of a bracket to mount something to a round 35mm rod without bending or drillig. It has a print in place hinge to mount it easaly on the rod and than you can mount anything flat to it.

3x M5 screws and nuts can be used to hold it in place on the rod.

I wanted the bracket itself as strong as possible so I coundn't desigt it thin enought to bend it round the rod nor shoud it be so short to just clip on it. So I designed this mildly overengineered bracket. Wathever you are screwing onto it will hold the hinge together so not all the load will be on the hinge itself.
