There is little storage space in my bathroom, so I designed this little basket that hooks on the inside of the under-sink cabinet doors.

This basket is designed to fit 3/4" (19mm) thick cabinet doors.

The parts are riveted together with four 3/16" (4.5mm) diameter rivets with 1/2" (12.5mm) depth of grip. I used two rivet washers on the back of each rivet to ensure plenty of contact surface area with the plastic.

You will need to print the basket and two of the arms to make one assembly.
