Dumbbell anti roller

My dumbbells kept rolling on the floor, not laughing, but making paint marks and not being very reliable. I wanted them to stay at one place. This model fits around a 2,5 kg weight plate / dumbbell. Inner dimensions are 160mm. Rescale as needed. Print as many as you need and put it around the largest plate you have on your dumbbell.
The tall version fits around a bigger area of the plate but takes more time to print. The lowest version is tall enough to function, taking less time to print.
