Withing 24 hours from getting the tool, my 8 year old son was able to imagine, design, & print, an idea of his own, 100% by himself. Quite impressive for both the tool & the kid!
Here it is: A snowman! He simply made 3 spheres, of different sizes, & positioned them on top of each other. OK, I helped him just a little by suggesting he add some cross bars at the bottom for stability, but he drew them in CAD by himself.
My daughter suggested we add a hat, eyes, and nose, for the "Snowman 2". Easy enough. Oh, and print it white, not black!
Here both kids are, quite happy with their creations.
