Originally designed by my son Benja (6yo) on Tinkercad, I helped him afterwards with some fillets and adding the narwhal on Fusion360. Wheels rotate very well and the skate is finger-playable.
He's now giving skates to all his friends (as a makercoin of sorts).

Benja started with Tinkercad and build the basic model albeit with sharp edges and corners. We moved the model to Fusion360 (import mesh and convert to body) and applied fillets everywhere.
