using a binder clip as a spring instead of 3d printing one

Thanks to both of you & OP, I wasn’t going to watch but these comments got me to click, & some of those subtle transitions were nicely done! The first one I noticed with the plastic coil spring in his hand zooming in was my fav.

The mixed 3D printing concept was nicely done. Sounded like it has a satisfying solid click as you close it. I can’t think of a reason I’d need this currently, but it’s making me want to try it out just for the sake of it!
