Here is the mighty Godzilla:

Here is Baymax, and a perfect example of my current problem.  I'm getting a very pronounced Z Ribbing.  It was as obvious on smaller models, or models with surface features, but on something like this with very smooth continuous surfaces, it's immediately visible.   I'll probably start a topic in the help section next.

And last but not least CATS.  this really nice model shows the same identical issue as BayMax.  Godzilla does too, but it's not as obvious as these 2 models dues to the many surface features.

what scale is it now? thats way long print. thanks for the cleanup tips. I wondered what error was as nothing is highlighted

I have no idea of the scale, since I didn't model it.  All I can tell you is the original model was huge, about 15 times larger than it is now.  I simply reduced it to fit on the Solidoodle print bed (200x200mm)

I suppose we can extrapolate by using the door as a reference.

So the average door is 80"x32", or 2032x813mm
The model's front door 31x16mm.  Not the same proportions (height to width ratio), but let's use the height for our calculations:  2032 : 32 = 65.55, so the scale of this house is approximately 1:66. 

"N" gauge is approximately 1:150, so reducing the scale down to 44% of what it is now, should give you a model that's approximately "N" gauge.

AS for the error in netfabb, if you go to repair, select status, then click update, you'll get this:

EDIT:
This scaled down model, without any support,with infill set to 5%, and infill only as needed checked, would take about 6 hours to print @ .1mm resolution, or about 2 hours @ .3mm resolution

I got the shack someplace b4. the Inn is bad in netfab, seems the 3 lights are not attached to anything, just floating in midair

Yeah, I know.  You should have seen all the errors it had to start with.  Anyway, the errors reference are a bunch of invalid orientations.  These are faces inside the model, and won't be a problem.

As far as the lamps are concerned, you can use NetFabb to extract them as separate parts and print them, then extrude a piece of filament to get a nice thin strand and use it to hang the lamps (or use string if you want them to dangle.)

The model slices fine with both Slic3r and Cura at .1mm and .3mm.  At the current scale and .1mm resolution, and depending on the amount of support you'll use, it will take about 60+ hours to print this model !

Here is also a model of an old time inn.

That changed last week when I came up with my tensioning device, so I finally got to print my articulated robot.  28 parts in all, fully posable.

So here I am.  I scanned myself using my Kinect scanner and Skanect.  Here are the results:

Here is a Bust of Ajax (at least I think that's Ajax)

Here is recent print (from last week): Totoro pen holder

This is one of the more complex models I printed, a fishing cabin and dock.  It has many overhangs and undercuts, as well as many small parts like the chairs, and hanging lamps.  Unfortunately, the chairs and lamps didn't come through clean, so I'll print them separately. 

The model was only roughly stripped of the support material, and needs a lot more cleaning.  I'll post new pictures when it's done.

got an stl of the cabin it would look cool on my train layout

The tall skinny guy (Han Solo)  needs to have the legs reprinted.  When I printed those parts I didn't have a fan running or a prime pillar, so the hot end lingered too long on the small parts and melted the material, creating those ripples.

The Satyr came out probably the best, after tweaking the support settings in Slic3r.  The buzzard and the little kid are pretty cool too.
