This little keyring is based on my larger Articulated Shenron v1 model. It has some articulation, but the legs do not move, and the neck doesn't move either due to the addition of whiskers.
I would not print it any smaller than the provided file. I also would not use it on items that go in a pocket or a bag. It's best used on the outside of a bag.
Only the 3MF has the "negative part" to make this a keyring; otherwise, it's just a smaller version of the Shenron v1 toy with built-in whiskers. RAW STLs also do not have paint data on them, and the 3MF may not open outside Bambu Studio.
If you'd rather not have it as a keyring, simply delete the negative cylinder part as shown in the picture, and you're good to go!
I printed mine without a brim, but if you have adhesion issues, I would suggest using one.
Supports are not needed for 99% of this model; do not use them or the model can break when you remove it from the supports!
HOWEVER; I have painted supports on the whiskers, as they float from the hotbed and would fail to print without them. Do not change the support settings, or you'll lose the manual painting I did. If for some reason the supports aren't there, or you're using the RAW STL, you can paint them yourself; just make sure it looks similar to the image and you should be good.
