Kaddy Clip

We have a solid surface shower in our Motor Coach. There is a small recess shelf for shampoo, etc... The problem is...that's not enough space for two peoples showering supplies. My wife found a wire kaddy which gives us extra space for holding shampoos, shower gels, etc... but it has a tendency to try to slide of the plumbing from time to time. 3D printing to the rescue. I've devised a small clip to keep the kaddy from sliding off...and hopefully give us years of service...without further malfunctions of the kaddy.
