Description
Kids can pour water into a cup and watch it run through ramps, cups, wheels and other small modules. It is a playful way to explore water flow, cause and effect, gravity, and simple experiments with water.
The system is made to grow over time. I plan to keep adding new modules, and the project is open source so others can adapt, remix, and improve it too.
All Flowplay modules can be used in two different ways:
This makes it easy to build a small water wall in the bath, in the shower, or outside.
The parts are designed to be easy to print. All modules print without supports. Only the small SKÅDIS hooks need support material.
I printed the parts in bright colors to make the water path easy to see and fun to rearrange.

This is a DIY 3D-printable bath toy system. I have tried to design all parts to be as durable and safe as possible, but I cannot guarantee complete safety and do not take responsibility for any damage or injury. Some parts are small and could pose a choking hazard. Always check printed parts for defects, sharp edges, or loose pieces before use. This system is intended to be used under adult supervision only.
