Drafting for mold injection

Hi guys,

I’m preparing a mold for 3D printing and need to apply a draft to the object that I’m casting on the mold. I figured I could do it with a simple deform modifier, but the object has a complicated shape and the modifier only creates a simple scaling on X/Y which doesn’t work for this case since it needs something more like the grow/shrink operator (but without the intersections).

Anyone here has experience applying drafts in Blender?


Can you post a screenshot or file?
