Pipe Holder

A part that holds a 3"-4" long section of smaller diameter tube within a larger diameter tube. The smaller tube outer diameter is about 0.75" and the larger tube inner diameter is about 1.5"-1.75". The part has a small circular ring that goes around the outer diameter of the smaller tube with three arms that extend radially outward and upward from the ring. When the smaller tube is pushed into the larger tube, the arms contact the inner sidewalls of the larger tube and flex inward/upward, thereby holding the smaller tube in place. I do not need to tube to be designed... only the ring and the arms ("the spider"). I want to 3D print the part for prototyping, and the material needs to be flexible with good elasticity to that the spider arms return to their original shape when the small tube is removed from the large tube. The rubber band is the pictures I provided represents the ring that the arms extend outward from.
