It's hot these days, good time to stay in the pool. So we do and my kids started their first diving trials yesterday. And quickly: "Daaaaad, we need something to dive.... can you print something?"
Sure. So here's my version/kind of an Pool-Fish. It's printed 40 Minutes and assembled with an M8-Nut in 15 Seconds. If you glue it they will stay on the water surface. If you just snap them togehter they will dive.
Happy diving... 8-)
