About the Yuma Territorial Prison
The Yuma Territorial Prison, in Yuma, Arizona, received its first prisoner on July 1, 1876, and closed on September 15, 1909. It opened under the authority of the newly organized Arizona Territory. Over its 33 years of use, 3,069 prisoners, 29 of them women, served sentences there for offenses that ranged from murder to polygamy. Construction and repairs went on continuously, with the prisoners providing the labor.
In 1909 the last prisoner left for the newly built Arizona State Prison Complex in Florence, three years before Arizona became a state in 1912. A year after the prison closed, Yuma Union High School, whose own building had suffered a fire in 1909, took over many of the old prison buildings. Classrooms were set up in the cellblocks, and the hospital became an assembly hall. The school stayed from 1910 to 1914, and after 1915 the city of Yuma requisitioned the stone complex as a city jail.
The site is a historical museum run by the Arizona State Parks system, called Yuma Territorial Prison State Historic Park. It was Arizona's third historic park, and it holds a graveyard with the graves of 104 prisoners. The National Register of Historic Places lists it among the Yuma Crossing and Associated Sites. Inmates included the stagecoach robber Pearl Hart and the Mexican revolutionary Ricardo Flores Magón.

- Low buildings, small details
- The prison buildings are low and the small raised building has thin posts and a hipped roof. A bigger print size keeps more of them, and Print friendly adapts thin parts to the print scale.
- A small arched gate
- A small arched gate sits between the two long wings. Layers of 0.12 to 0.16 mm help it stay readable, especially at a larger print size.
- One piece with the ground
- The Yuma Territorial Prison is joined to the ground in the exported file, and the four-side check found no floating parts, so nothing needs gluing.
- Pick the detail for your nozzle
- In the Buildings settings, set Landmark detail to Print friendly to adapt thin parts and small details to the print scale. Full detail keeps every modeled feature, for larger prints or a finer nozzle.
- Colors
- Buildings, roads, water and ground arrive as separate filament slots in the 3MF. The Yuma Territorial Prison takes the building color.
- File format
- You get a 3MF for Bambu Studio, OrcaSlicer or PrusaSlicer. Any of them can save it as STL if you need one.
