Pyramid with base, angle 51.5, hollow

thingiverse

Made with FreeCAD Update note: there are now two files available. A smaller version (4.5x4.5cm) has been added, featuring the same 1.3mm thick walls to prevent thin walls when downscaling the original larger sized 14cm pyramid. Printing is incredibly easy, requiring no raft or support and saving filament in the process. This design represents the simplest hollow pyramid with a face to base angle of approximately 51.5 degrees, similar to the Great Pyramid's angle found at Giza, Egypt. It features a 2cm high socket or base and the original scale of the pyramid is 140x140x88 mm with 1.3mm thick walls, which is relatively thin but still printable without support. The main purpose of this design is decoration. With the socket, printed at the original scale it will be 108mm tall. When downscaling, use the smaller pyramid found as the 4.5cm STL file so that walls will be thicker. Although you could still downscale the larger one if you want a super fast print. There are small ventilation holes in the square base and two smaller ventilation holes near the top to help deal with sun exposure and humidity caused by varying air temperatures. For optimal results, align the pyramid with magnetic north for the best time machine effect and correct levitation - although this is purely humorous. Glowing PLA filament was used for added visual appeal. Print Settings Rafts: No Supports: No Resolution: 0.3 Infill: 15%
