Our story behind
My 8-year-old son got an HP Otto for Christmas, and he and I started learning the basics of coding together. At the same time, we’re also learning 3D printing and having so much fun while we try, fix, create, and brainstorm...

I’m learning from scratch and improving with every mistake, so your feedback is more than welcome. 😉
Thank you, and enjoy this model. ❤
