This is a kickstand to fit a Spigen phone case for a Samsung S21FE. I am not sure if there are other models it will fit. I don't believe the kickstand is compatible between all the Spigen cases. I have included a fully parametric Fusion 360 file if you need to modify it for a different model.

It did fit a little tighter than the original, but I'm sure that will vary with printer calibration and a bit of scaling or tweaking is to be expected for such a small part.

I was able to print it with reasonable and usable quality using a 0.4 nozzle and a 0.15 layer height using orange Prusament. It does seem like this might be a good application for a resin printer if you have one. (I can only imagine.. I've never owned one)

I printed it in the orientation shown in the STL. I enabled supports to support the posts on each side of the hinge. Rotating it to print on edge is not recommended as the posts will end up being a lot weaker.

Note: The STL marked “no pin” just has a hole all the way through it where the posts should be. This is in case you'd prefer to insert your own metal pin (maybe cut a piece off a paper clip?). This one should print fine with no supports.

What good is this: Well, I guess the most obvious scenerio is if you lose or break your kickstand somehow. In my case I made it because someone at my work ended up with the same phone case as me, and I wanted something to make mine look unique so that they wouldn't get mixed up. I was thinking about adding my name to it, which I may do in the future, but for now just being orange should help.
