Knowing the basic scale of the model, you just have to divide it by the target scale to obtain the resizing ratio to apply in your slicer.

For example, the file is provided in 1/56 and you want to print it in 1/72, so you just have to resize it by a factor of 56/72=77,8% in your slicer.

Yes, most of our sets are designed with this in mind, by being divided into several parts: this allows easy access to the interiors of the ground floor and each floor. You can consult the photos, which systematically detail how the file is designed. 

We also detail the number of pieces that the decor contains, you can consult this information by clicking on "Product details" of the product sheet: 

We compress some of our large files so that they can be downloaded more easily and quickly. To do this, we use one of the most common and efficient compression methods, the RAR format.

To open the RAR archive and access the STL files, you have two methods :

- either use one of the many free software available. We recommend 7-zip (download here: 7-zip.org). Once the software is installed, you just have to extract the files contained in the RAR archive.

- or use an online website, like this one: https://extract.me/

With 7zip, you just need to right-click on the RAR file, then "7-zip" and "Extract to ..." :

An example of how RAR archive is useful : a 552Mo size folder is only 159Mo when it's RAR compressed (-72%). It's definitely easier to download ! 

The scale in which the file is located when you download it is indicated in its product page, at the "Product details" level ("Original file scale") :

If the information is not present, do not hesitate to contact us, we will communicate it to you as well as the resizing ratio of the model to the scale you use. 

Note that some slicers may automatically resize objects when you import them: identify it when it happens to be sure to apply the right resizing. 

The 3D models can be resized to any scale for printing, they are specifically designed for wargaming, so they are perfectly suitable for scales from 10mm to 32mm. We advise you to pay attention to the size of your printer board if you want to print the scenery in large scales.
