Print 1 each of parts A,B, and C. Sand parts A and B until part B slides easily into part A.
Use a string to pull a rubber band through the hole in the bottom of part A. Pull the rubber band through the top of part A. Slide the rubber band into the slot of part B. Slide part B into part A. Part C installs into the bottom of part A to keep the rubber band from pulling through.
To use this on a Walmart shopping cart...... Push the part onto the rounded / metal part of the shopping cart handle. Then slide it over the plastic hand grip. Put your phone into the holder and enjoy using both hands while shopping.
