Fix for broken fan angle snapping hinge on this fan model. The fan would droop, and now it will stay at angle again!

I got this fan at Walmart and soon it would flop down instead of staying at the angle I set it to. It was too easy - something just pushed the fan too much in the wrong direction and it snapped a little cylinder in the hinge which held a spring-loaded metal piece that would snap in place to hold the position. The cylinder piece was not anchored very well in the first place.
So it wasn't a great fan, but still -- why waste it? Originally I had wanted to just print one someone else made but, not finding any models yet, I made one myself.
I made it with Build123d python library, which is much like OpenSCAD, but python, which I really like. There's a VSCode extension called OCP CAD Viewer that is great for working this way.
Instructions
Remove the round plastic cover pieces on the sides of the fan.
Unscrew the center screw only - keep track of all 3 components (screw, washer, and lock washer)
Carefully pull off the base from the side of the fan. 3 pieces should be under there - the plastic cylinder, the spring, and the metal locking piece.
Put the spring and metal piece into the printed piece. Make sure the metal piece can slide through the printed piece. My printer isn't super optimized, so for me, I used an awl to scrape the inside of the hole so it slid better. Remove the spring and metal piece for now.
You may want to do a dry fit of the piece into the fan and mark exactly how it lines up - matching where the pin was before.
Apply some sort of adhesive to the back of this printed piece (I used some thin double-sided tape that came with plastic insulating sheets for windows, but you could use almost anything -- super glue might be alright, caulk would probably work fine, JB Weld, etc.) Mostly it just needs to keep this piece from rotating, but there should be a fair amount of pressure from the screwed base to hold it to the fan.
Carefully place the printed piece onto the fan - lining it up correctly.
Place the spring, then pin into the printed piece.
Put the base side back on and screw it in.
Put the cover cap on and you're done!
I hope this helps someone else get longer use out of their fan! It's a simple/dumb model, but I sure do love not having to throw away the fan, or live with it flopping down all the time.
