Jeep CJ/DJ Wiper blade adapter

thingiverse

I designed this windshield arm adapter specifically for old stock arms with a lazy "S" spade end. Once the arm is inserted into the adapter, it then securely clips onto the wiper blade. For added peace of mind, an M3x10 screw can be inserted underneath in case the attachment comes loose. Update 6/27/2019: I enhanced the design by adding more material around the screw hole and replaced the original STL file with a new one. I also included cross-section pictures for better visual understanding. The old wiper blade had a piece of spring steel in the area where the spade end inserts, which helped maintain tension on the arm. You may need to make some adjustments; the new pictures should help you visualize the design and provide ideas for future improvements.
