This downloadable file includes the STL files necessary to print the frame of the MAC-10, replicating its iconic compact design. For optimal results, print with high infill settings (50-80%) to ensure structural integrity, especially given the frame's intended use in a firearm context. We recommend using durable materials like PETG or ABS to withstand stress and provide longevity.

Special considerations include ensuring proper layer adhesion and post-processing for a smooth finish. Refer to the provided assembly guide PDF at The Big Mac Assembly Guide for detailed instructions on assembling the printed parts with additional hardware.

Printer Compatibility & Settings

The Big Mac - 3D Printable MAC10 Frame is compatible with most FDM 3D printers capable of handling detailed designs, such as Ender 3, Prusa i3, or similar models. Recommended materials include PETG or ABS for their strength and heat resistance, crucial for a frame inspired by a firearm design. PLA is not advised due to its lower durability.

Suggested print settings include a layer height of 0.2mm for detail, a nozzle temperature of 230-250°C for PETG (or 240-260°C for ABS), and a bed temperature of 80-100°C. Ensure proper bed adhesion with a brim or raft to prevent warping, and consider using an enclosure for ABS prints to maintain consistent temperatures. Always prioritize safety and check local regulations regarding 3D-printed firearm components before proceeding.
