Reply to "3D Printing... Repository ..."

I have a question for the group.  I have been making O scale 3D prints for a couple of years.  However I consider my quality standards for my use as 'good for background' use.  So here's the question How good is good enough for posting?  Is there some notation that I can but on things I post as good for background?  IE I have a machine shop that sits in one corner of the layout, and you can kinda see inside.  So I made some lathes, work benches, etc.  They are NOT super detailed they simply represent what 'should' be there.  From a distance, they do the job.  Some examples.  Russ
