This little keyring is based on my larger Articulated Kohaku River Spirit 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.
I have optimised the 3MF for printing on the BambuLab X1C; it can print up to 5 keyrings at the same time and generates the same waste as if you only printed 3. See the video of 5 being printed at the same time:
Due to the limit of 4 colours, the pupils are not black. A dab of acrylic or permanent marker works fine.
Only the 3MF has the "negative part" to make this a keyring; otherwise, it's just a smaller version of the Articulated Kohaku 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! (both Kohaku and Shenron have the hole in the same place)
I printed mine without a brim, but if you have adhesion issues, I would suggest using one. Supports are not needed on this model; do not use them or the model can break when you remove it from the supports!
