My son designs his own toys in Tinkercad over the last few years. He's 7 years old now and this is his latest creation. Usually we print them out when we attend Midwest RepRap Festival or MakerFaire. COVID-19 has postponed MRRF, but he wanted to make one anyway.
I made a couple of tweaks to make parts easier to print, but otherwise this completely his design.
Most of the parts are glued into place with CA glue. The propeller and the mast will rotate though.
