Coin Operated Supermarket Cart Releaser for USA Quarter Shopping Trolley

thingiverse

To avoid leaving your child unattended, use a quarter from a supermarket cart dispenser instead of an American one. This way, you won't have to retrieve your original quarter. Before this invention, you may have had to sacrifice your quarter. A neat solution! Don't forget to visit 3dPrintFileMarket.com for more cool 3D print files, including CartRel2.stl for reinforcement and attachment to a keychain. Enjoy! Remember to use Replicator Slicing Defaults, default start/end gcode, and Print-0-Matic. No raft/support is needed; set infill at 99%, layer height at 0.25 mm, one shell, 41 mm/s feedrate, and 56 mm travel feedrate. The print temperature should be 220 C. To use the product, insert it into the supermarket cart's coin receptacle, rotate it 90 degrees on the z-axis, and retrieve it.
