Making mold design question

i have a model but i feel difficult how to make mold.
problem is after finish mold work when i pull out this how to pull out?
it looks like some difficult model for molding.y2.stl (673.3 KB)

This could be 3D printed directly which would be the simplest approach.
To make a mold to produce this would be more complex because of the undercuts. Maybe 2 part outer silicone, and a flexible (silicone) central core.

It’s also tiny - seems like a direct print would be the easiest.

The model also looks like it needs to be more precise as the vertical posts are not aligned to the rings.


thanks for advice ! :slight_smile:
