3D Printable AR15/AR9 80% Receiver Milling Jigs by CTRLPew Parts

This downloadable file includes the necessary STL files to print the milling jig components for finishing 80% AR15 and AR9 lower receivers. Designed for durability and precision, these parts are critical for achieving a professional result.

For optimal performance, print with a high infill percentage (50-75%) to ensure structural integrity under milling stress. We recommend using strong materials like PETG or ABS to withstand the forces involved. Be sure to follow the provided build instructions for assembly, available as a PDF guide.

Printer Compatibility & Settings

This jig is compatible with most FDM 3D printers capable of handling detailed prints, such as Ender 3, Prusa i3, or similar models. For materials, PETG or ABS is highly recommended due to their strength and resistance to deformation during use.

Suggested print settings include a layer height of 0.2mm, 50-75% infill, and at least 3-4 wall layers for added durability. Ensure proper bed adhesion and consider using a brim or raft for larger components to prevent warping. Always double-check your printer’s calibration to maintain dimensional accuracy for a precise fit.
