This is a Bin bracket I made to lift the bin in our caravan off the floor so it wasn't getting licked around. the centre table post is around 57-58mm in diameter and I've made the bracket slightly oversize so I could place a sheet of paper in between the bracket and the post to stop the post being marked by the bracket. to attche to the bin I suggest using Pan head bolts so there is less to catch the bin liner. I also fitted nylock nuts to the bolts to stop them vibrating loose. Print standing up with no need for supports.
