Cannot compliment Moi3D enough for the exceptional user interface and incredibly easy to use toolset! With a little coaching, my 6-year-old grandson created his first 3D CAD model within 20-30 minutes which we subsequently used to 3D print his pencil holder. The following day he repeated the design from scratch (mostly by himself) so we could 3D print one for his 5-year-old cousin. I'm still smiling... such fun!

Cheers
