3D Engineer Castle
This is a 3D US Army Corps of Engineers castle. This model originally came from the US Army Corps of Engineers Sacramento District website (https://www.spk.usace.army.mil/Media/3D-Resources/). I had issues with the STL file so I had to re-export it from Blender to get a file that sliced properly in Cura.
Technically it should be printed in crimson red but of course it will work in any color.
The actual model is pretty small so you'll probably want to scale it to 300% or greater before printing. I printed using PLA with 10% infill and it turned out great. Here is a an example video of a print of this: https://youtu.be/W_oOHLTZDDY
Enjoy!
