I made a 3D model of a seal using Meshroom and thought I'd have a go at 3D printing it. Is there an easy way in Blender to a. Identify what issues there are with the mesh in terms of 3D printing and b. How to fix them. I'm thinking of some kind of auto fix tool. I've watched a few videos and it seems like it could be quite complicated so want to check if there is an easy fix before I investigate further.
