I retraced this design https://www.thingiverse.com/thing:1326207 by Davidd26... in Fusion 360 mainly because there is a lot of exessive material in that model and I wanted to explore sculpting.
I sliced my model and the reference with 1 shell, 20% infill no supports:
reference design: 820g, My design: 370g.
For anyone interested in the Fusion model, give me a sign.
Only use support on the eyes and mouth, the rest printed without supports with minimal stringing.
I also changed the XY scale to make it wearable for my kids.
Ive printed with 3 shells outer and inner for rigidity.
