The things I am designing are more decorative with highly sculpted meshes so I think that may be create additional challenges. Leave it to me to make things even more complicated. ;-)
Errors on Boolean operations in blender only happen on non-manifold meshes, ie not watertight. If you netfabb it first there should be no issues.

Tinkercad as stated above can do it also, but what Tinkercad is bad at is dealing with high poly meshes - it can perform booleans on them but it can crash the webpage pretty easily if they are super complex.
