This is a standard 60mm MIL-STD-1913 Picatinny rail section. It is designed for airsoft use, featuring two mounting holes specifically clearanced for M4 countersink bolts to ensure a flush, snag-free surface for your optics or grips.


Print Settings

To ensure the rail teeth meet the tight tolerances required for accessories, use the following:

  • Layer Height: 0.1mm – 0.16mm (Critical for accurate "slope" geometry).

  • Perimeters: 4 minimum (You want the "teeth" and bolt seats to be solid).

  • Infill: 40% - 100% (Gyroid recommended for impact resistance).

  • Supports: None required. The 45° undersides are designed to print cleanly.

Material Choice

  • ASA / ABS: Best for outdoor use and heat resistance. Note that these materials shrink (approx. 0.7%–1.5%); if your rail feels too short or thin, adjust your horizontal expansion in the slicer.

  • PETG: Excellent toughness and UV resistance. Easier to print than ABS but slightly more prone to "stringing" in the bolt holes.

  • Avoid PLA: It will soften in a hot car or under direct sunlight, causing your accessories to lose their shape or fall off.


Technical Dimensions

  • Total Length: 60mm

  • Slot Width: 5.23mm (Standard)

  • Hole Type: M4 Countersink (90° head angle)

Warning: This is for Airsoft/Paintball use only. Do not use 3D printed rails on real firearms as the recoil and heat will cause immediate mechanical failure.
