This is a cool fidget. No moving parts. Great for kids to rub their fingers on to feel the bumps of the tyre print. I had a sharp corner on one - or a blob so take care to check the print that it is actually smooth and free of print poop before giving it a go! I thought next time I'll print mix and match colours - the model is flexible enough that you can have the base/cover one colour and the tyre print another colour if you are into contrasts!

This model prints very well! I changed the colours a bit and also printed the koala with a gold heart. Very clear and well designed!
