As both Bittle and Lego are often used in STEM education, I designed a 3D-printable back cover that is compatible with Lego bricks! https://www.printables.com/model/795047-petoi-bittle-lego-cover Wouldn't it be cool to have this as an official accessory? Lego's patent expired some years ago, it opens up so many possibilities.
That's very cool. I'll test it tomorrow.
Would you mind if I added it to this collection with credit to this post?
