Here is a toy that I designed for my daughter. It simply consists of a male and a female screw head in one design, making them endlessly stackable and easy to twist together.The toy is 40mm in diameter, making it a safe and enjoyable size for toddlers to play with. If you’re looking for a fun desk fidget toy, you can print it at 50% scale for a smaller version. This design is directly inspired by the StackBolts by Cameradactyl: https://www.cameradactyl.com/buttergrip/cameradactyl-rex-8pyd8
