紅樹 タカオ (@mongonta555) is an expert in both software and hardware and is on his way to building a little fluffy robot park.

He was inspired by tweet from @robo8080 to start building cat-ear options for Stack-chan.

At first, the design was difficult, but thanks to his openness about the process, he was able to get advice from other makers and gradually refined it.

In the end, he finally succeeded in creating a removable cat ear option!

After ears, guess what's next? Yes, tails! He even went on to make an extra bracket for the tail!

The tail is equipped on top of a third servo motor, so it moves. Wow.


Since I made the 3D data available early on in the development of Stack-chan, many community members have been modifying the case and adding optional parts like his works.

Among them, He contributed by creating a case that is compatible with the official module of the M5Stack, which is used in the example above. Although it takes up some extra space compared to the dedicated Stack-chan board, the ability to divert the official module makes it even easier to assemble, making it a useful reference for other community members.

His modified version of the data is available as a pull request in the repository (to be merged in the future).
