I can't give thickness to this shape

ShoeSmall.3dm (703.3 KB)

Hey guy! I made this skin of high heels and I can’t figure out how to give it thickness. It needs to be at least .5mm, but whenever I try to offsetsurface or offsetmesh, it comes out messed up especial in rendered view. I don’t care about it being a Solid as long as it will export for 3D printing in STL.

Hello Aiden,

Try offsetting the mesh in small .1mm increments.
Thank you,

Nah still no good results
