Bring the Cincinnati skyline into your home in true 3D! These make for the perfect gift or home decor for residents, travelers, and admirers of the city.

**This listing includes two different sizes - Large and Extra Large. The Extra Large size contains four tiles to print individually, for combined pieces larger than your build plate!**

_Subscribe to keep an eye on the **new models we release each week**!_

**Steps**:
1. Import the STL to your slicer. 
2. Scale the X or Y dimension to the desired size with 'Uniform scale' checked.
3. Print as one-piece or split into tiles in the slicer for larger sizes.
5. Slice and print!
6. Set on shelf, tabletop, or hang on wall with sticky mounting strips. 
7. Optionally, stylize it with a frame and background mat or multi-color print in your unique way!

**About the models**
These are the most detailed and accurate 3D-printable cityscape and landscape models available. Each is designed and optimized from Micropolitan's 5+ years of experience developing and selling 3D prints of iconic locations worldwide. Each model is designed by hand, using a combination of data and reference imagery. We use LiDAR and refine the architecture, block by block, using digital sculpting tools and satellite imagery. The models are then optimized for detail preservation while keeping the file size manageable for everyday computers.

**Making your piece**
These make perfect centerpieces or collections for your home, to document your travels, or as distinct and unique gifts. Many design options are available - framed and unframed, for wall, tabletop or shelf display. They can be printed in a range of sizes with stunning detail, typically from 6"x6" up to 12"x12"+. The model can be cut into 4+ tiles to print and assemble a piece larger than your build plate. 

- Size: Scale to at least 150x150mm to preserve details.
- Layer height: 0.18-0.25mm
- Nozzle: 0.4-0.6mm
- Infill: 15% Gyroid
- Walls: Arache OFF (Classic ON)

**Styling and display**
These look great framed or unframed! They can be displayed on tabletops, shelves, or hung on the wall with mounting strips. They look best when lit from the side. Display near a window, lamp or downlight to make the 3D features pop.

**Materials**
Filament: For a minimalist look and best grayscale shadowing, use a matte white PLA. Marble and silky filaments are also popular looks.
Frames: Choose a frame or shadow box that fits your print dimensions.
