The Schlank Flügelmann (SF5) - 3D Printable Universal MP5 Build Parts

This downloadable file includes essential STL files for creating your MP5 build, such as the SF5 Upper Receiver, Lower Receiver (caliber-specific options from 10 or 40 Folder), and SF5 Endcap (Pic Rail or Swarmtech variants). The Swarmtech Folding Brace files are also provided in the main build directory for easy access. For optimal results, print with high infill (50-75%) to ensure structural integrity, especially for load-bearing components.

Consider using durable materials like PETG or ABS to withstand the mechanical stress of firearm use. Ensure proper layer adhesion by adjusting print temperatures and bed leveling. Detailed build instructions are available as a PDF guide at the provided link for step-by-step assembly.

Printer Compatibility & Settings

The Schlank Flügelmann (SF5) build is compatible with most FDM 3D printers capable of handling medium to large prints, such as Ender 3 or Prusa models. Recommended materials include PETG for its balance of strength and flexibility, or ABS for higher durability, though proper ventilation is required due to fumes. Avoid PLA due to its lower impact resistance, which may not suit firearm components.

Suggested print settings include a 0.2-0.3mm layer height for detail and strength, 50-75% infill for robustness, and a heated bed to prevent warping. Ensure your printer’s build volume can accommodate the larger parts like the upper and lower receivers. Always double-check calibration to avoid dimensional inaccuracies during printing.
