Bathroom accessory holder

My original one was broken, so I designed a new version thats fits better to my needs. I use soap-shampoo of 60mm diameter and a bottle of liquid body-soap.

my original adapterring was ok, its just an cirle segment that gets wider at the end, so the holder squeezes it and it may stay at any height of the rod.
So maybe you need to create one that fits to yours - or tell me, I try to help if you cannot do it.

I tiny bit support is needed for the Adapterlimiter.
