Mac n Cheese v1.5 M11 Receiver Parts

The Mac n Cheese v1.5 M11 Receiver file package includes all necessary STL files for printing the lower receiver components. Key parts include the main receiver body, a front version compatible with Lage uppers, and a tail cap designed for metal picatinny rails. For optimal results, refer to the separate “SuggestedPrint...” file mentioned in the README for print orientation guidance.

It’s recommended to use high-strength materials like PETG or ABS to ensure durability under stress. Pay attention to layer adhesion and infill density (suggest 50-70%) to maintain structural integrity. Always double-check local laws before manufacturing, as noted in the README by Middleton Made 3D.

Printer Compatibility & Settings

The Mac n Cheese v1.5 M11 Receiver files are compatible with most FDM 3D printers that have a sufficient build volume to accommodate the receiver dimensions. For best results, use printers with a heated bed to prevent warping during long prints. Brands like Creality, Prusa, or Ender are typically well-suited for this project.

Recommended materials include PETG or ABS for their strength and heat resistance, though advanced users may opt for nylon for added toughness. Suggested print settings are a layer height of 0.2-0.3mm, infill of 50-70%, and a minimum of 3-4 wall layers for durability. Ensure proper cooling and bed adhesion to avoid print failures, and consult the provided build instructions PDF for additional guidance.

Conclusion

The Mac n Cheese v1.5 M11 Receiver is an exceptional choice for 3D printing and firearms enthusiasts seeking a reliable, customizable lower receiver for the M11 9mm upper.
