3D printed rain is popular, and here is my little take. It is simply a happy cloud with rain.
It is an easy, quick print. A great test to see how good your printer is at making bridges. No supports needed. The cloud can be glued to the rain, if you wish.
Use it as a fun little forecast for kids. If it will rain today, put the raining cloud on the shelf.
Thanks to 3DPrintBunny for the inspiration:
