The rectangular "Upper Pattern" (model 6145) STL

The rectangular frame model 6145 features a vertical orientation and complex composite geometry: an oval insert is integrated into the strict rectangular profile, forming an additional inner field. The upper section of the frame is crowned with a developed decorative cartouche consisting of symmetrical volutes, scrolls, and floral elements. Frames with a pronounced emphasis on the upper crest became widespread during the Baroque and Rococo periods, when French mirror-makers learned to cast large-scale mirror plates, necessitating heavy carved wooden frames to secure and visually anchor the structure on the wall. The model is intended for framing wall mirrors, paintings, tapestries, portraits, and creating accent interior elements.

The digital 3D model is provided in STL format and optimized for milling on CNC machines. The relief is adapted for processing solid wood, MDF, and modeling board. Toolpath generation for machining can be performed in specialized software environments, including ArtCAM, NC Studio, and Mach3, ensuring compatibility with both desktop and industrial CNC milling equipment.
