3D Printed H&K UMP 11/9

UMP Up The Jam.

When H&K named their now famous PCC the “Universal Machine Pistol,” I’m not sure they had Mac uppers in mind. The UMP 11/9 is a culmination of several years of hard work and dedication, bringing the design features of the iconic German carbine and the reliability and flexibility of the Mac platform together to make a package that makes my mouth water.

Brought to us by MPRTech and DB Firearms, experienced devs with many famous releases under their belts, this project promises to be the best of both worlds without any compromises. At long last the community’s addiction to German Space Magic will be sated.

For now, anyway.

UMP 11/9 Technical Specs

The files are designed to accommodate PLA+ as a minimum, though two components are designed to be printed in TPU to avoid wear. Documentation also recommends specific print settings. Durability may vary depending on selected print settings and printing materials.

The design makes use of a Mac 11/9 upper and a standard AR-15 lower parts kit, as well as Sten-pattern magazines. This design is also compatible with magazines used in the Sten version of the DB Alloy.

Included in the package are 4 different variants:

  • Standard – Full sized, recommended for printers larger than an Ender 3
  • Micro – Compact, recommended for smaller printers
  • Reinforced – Makes used of FGC Reinforcement plates for additional durability
  • Braced – For use with a folding pistol brace
