Toucan Workflow: Post-Processing
MeshMixer
Autodesk MeshMixer for final cleanup. (Note: Download is weird — hosted on Internet Archive, UI from 2017, but it works well. Bit of a timecapsule as it is an app for 3D printing and has presets for a slew of printers from 2017).
Inspector
MeshMixer UI
MeshMixer has all kinds of interesting options for manipulating the mesh.
In this case, I want to fix the holes in the mesh to make the object a solid shell.
To do that, select Analysis → Inspector.
I usually use Minimal Fill as the fill mode.
Once done, export the STL and it is ready to print (or whatever)!
