Amidamaru

Amidamaru Spirit Ball Form Stl, not tested. You have to rotate and use support, scale it to the desire size (some parts are big).
I think it will look good printed with transparent filament

I printed in the size of the file. Is too small (17mm diameter). I used a wire to joint the left and right pieces. looks good enough
