I was asked to quote a file repair job for a student that had access to a 3D printer. To save him money (because we have a soft spot for students) I offered to show him how to prep the SketchUp file for free.
The model looked good in SketchUp, and appeared to have no reversed Normals (backward facing surfaces), but it contained an amazing number of open edges, which is typical for Sketchup Models.
Depending on the type of model you are attempting to print, you may be able to simply send the model up to CADspan and have it take care of everything. In the case of this model, I would segment the model first to retain every bit of detail possible. Because this model is obviously a collection of separate buildings on a base, I would separate the buildings one by one and process the base separately, or slice the base in to pieces the carry over with each building. If you opt to cut the model, adding a large plane, selecting it, right clicking ad choosing intersect with model,...
To start, all of CADspan is free.
We want you to have a good experience so we do not restrain your trial in any way. Feel free to enjoy full access to CADspan PRO for a month and see if it can save you time and money. After the first month you have two options. You can continue to use the processing features in the SketchUp plugin for free, though free users can only process a single file at a time, or you can purchace CADspan as you need it.

In short- You unzip the folder and your STL is inside.
The long version- In order to expedite the download process, the STL files are shipped to you in a compressed folder. As the name suggests, the compressed or zipped folder makes the file smaller and dramatically reduces your download time.
To uncompress or un-zip the folder:
PC- Right click on the folder that you have downloaded from CADspan and select "Extract" Follow the prompts and you will end up with an uncompressed folder containing your STL file.
MAC- Double-click the zip file and the file or folder will be decompressed into the same folder the compressed file is in. The new decompressed item will have the same name as the original file.
The CADspan toolbar is composed of seven icons. From left to right they are: Layerize, Unsmooth Model, Preview Style, Resurfacer, Import Geometry, Export Raw STL, and Thickness Calculator.
Layerize - This tool blows through SketchUp's groping and component hierarchy to take a selection and apply it to a selected layer. If you are familiar with the layer controls in other modeling packages, SketchUp's decision to have the layer of a component or group override the surface or line layer selection can be a bit confusing. The Layerize tool helps users blow past this hierarchy so that you can dictate a section of a model to be placed on "Part 1" and the rest of the model on "Part 2" so that you can easily segment your model to upload it to CADspan in intelligent, contiguous sections, rather than sending it in bits and pieces dictated by groups.
Caution: this is not easily undone. Saving your model as Project_Layerize.skp is a good idea before using this tool.
