Do you think a 16/17/18cm (ish) one would work between two? I am also sceptical of the trixie ones set up? It was just two bits of plastic I sloted together and I felt it was hard for even me to move as a person, I feel like there should be more moving parts to it.
Amazon has this 18cm one which could be good but I’ve never seen these before it has a bearing in it which is what I expected with the trixie one.

This one is slightly smaller but seems to be a more popular brand. If they're reliable and this is big enough I might just go with this.
