2003 Toyota Gas Tank Ball Joint with clip feature 8mm X 10mm hole

I Designed this Item using Free Cad. It interfaces with a square hole that is 8mm by 10 mm. The ball joint is caught by a double spring steel clip that acts like a socket for the ball. The clip art o the file interfaces nicely with the square it goes in but you have to push pretty hard. I printed this on its side! I would highly recommend that and do 35 percent infill. its a quick print, it only took about 15 minutes to print with .2 detail at 260 C. I have an Elegoo Neptune 4. The print was sliced with Orca so I think the fastest it traveled was like 150 mm/s
