Overview: Malorian Arms 3516 Prop

The Malorian Arms 3516, Johnny Silverhand’s iconic pistol from Cyberpunk 2077, is a popular choice for prop replication. Several STL models are available for 3D printing, with some offering enhanced detail and assembly methods. Notably, a remixed version by Grigi provides a screw-together assembly, allowing for disassembly and improved accuracy compared to the in-game model. This particular remix is designed to be FDM printable, even on smaller machines like the Prusa Mini, with most parts pre-oriented and equipped with support and seam suggestions for Prusa Slicer.

The model incorporates several features to enhance realism and functionality, such as a movable slide that closely mimics the in-game action, and integrated spaces for electronics. It also addresses details like the “ring-like thing” on the slide, which is often overlooked in other models, and includes three variants for the main frame’s side details and two for the rotary component (text in/out). A bullet can be inserted into the barrel from the rear, and another can be placed under the slide, which can also serve to conceal electronics.

Integrating LEDs and Electronics

A key feature of advanced Malorian Arms 3516 prop STLs is the provision for integrating various electronic components, including LEDs and even a laser. The design allows for the placement of three or four distinct electronic elements, powered from the magazine.

Specifically, the model includes:

  • Signature LEDs: Two signature LEDs can be housed within the rotary mechanism, with sufficient space allocated for a battery to power them. These LEDs are designed to rotate in sync with the rotary part.
  • Grip LEDs: Two red LEDs are intended for placement on the top of the grip.
  • Front Pod LEDs/Laser: The front pod area can accommodate two to three LEDs, or alternatively, a 12mm diameter laser. While a laser in this location might not be entirely game-accurate, it adds a “cool” visual element. This housing includes a patent and a locking mechanism.

The hollowing of the rotary component specifically facilitates the integration of these electronics, ensuring a clean and functional setup.

Assembly Tips and Materials

Assembling the Malorian Arms 3516 prop, especially the screw-together versions, requires careful attention to detail. A video guide is available to assist with the specific order of screw assembly. While superglue can be used in many areas, the design prioritizes disassemblability.

Recommended materials and hardware for assembly include:

  • Screws: M3 screws are primarily used, with most being countersunk. Specific lengths and quantities are suggested:
    • 5 mm: 2+2 pieces
    • 10 mm: 2+1 pieces
    • 16 mm: 5+2 pieces
    • 20 mm: 5 pieces
    • 20-30 mm: 2 pieces
  • M3 Nuts: 6+5 pieces, with options to add two into the grip and some to the spring mechanism.
  • Spring or Rubber Band: Essential for the slide mechanism to function correctly. Without it, the slide will not stay in place. The barrel component, where the spring connects, offers four length options.
  • Weak Glue or Glue Pads: A small amount can be used for minor adhesions if desired.

The magazine is designed to snap into place, eliminating the need for magnets. Similarly, the slide’s new spring/rubber mechanism removes the requirement for magnets there, and the rotary part is merged, also negating the need for magnets.

Paint and Finish

Achieving an authentic look for the Malorian Arms 3516 prop involves specific painting techniques and color choices. The original prototype was printed on a Prusa Mini, while the final version utilized a Formlabs Fuse 1, with the grip printed on a Phrozen Sonic Mini 8K.

Suggested paint colors and applications are:

  • Magazine and “Shine Things”: Revell enamel steel (91).
  • Grip: Revell enamel satin purple red (sm 331), painted on the inside for a distinct finish.
  • Other Parts: The base color for the remaining components can be the natural color of the PA12 material if printed on a Fuse 1.

The lettering on the gun, excluding “Malorian,” uses a custom-made font, as the original game font was unknown to the model creator. This custom font, including only the characters used, is typically provided with the model files.

Remix Features and Improvements

The remixed Malorian Arms 3516 model offers significant improvements over previous versions, focusing on game accuracy and practical assembly. Key changes include:

  • Screw-Together Assembly: Most of the pistol can be assembled and disassembled using screws.
  • Accurate Slide Mechanism: The entire slide, including the “ring-like thing” (slidefront), is integrated correctly. The slide and its contact points are modified to allow for a significant pull-back, similar to the game, and to accommodate a spring/rubber.
  • Barrel Modifications: The barrel, where the spring connects, has been modified and offers four length options for the spring.
  • Slide Endstops: Includes one fixed and one optional endstop for the slide.
  • Hollowed Rotary Component: The rotating parts are merged and hollowed out to create space for electronics, ensuring the LEDs rotate with the mechanism.
  • Light/Laser Housing: The front light/laser housing on the left side features a patent and a locking mechanism, designed to fit a 12mm diameter laser.
  • Hidden Handle Screws: The screws for the handle are concealed.
  • Accurate Side Protrusions: The elements protruding from the side of the frame are placed precisely according to game references, with three variants provided.
  • Custom Lettering: All text, except “Malorian,” uses a custom-designed font for accuracy.

FAQ

Q: Can this Malorian Arms 3516 prop be assembled without glue? A: Yes, the design emphasizes screw-together assembly, allowing for disassembly. While superglue can be used in some areas, it is not strictly necessary for most of the construction.

Q: What type of screws are recommended for assembly? A: M3 screws, mostly countersunk, are recommended. Specific lengths and quantities are provided in the model’s documentation.

Q: Is a spring or rubber band essential for the slide? A: Yes, a spring or rubber band is crucial for the slide mechanism. Without it, the slide will not be held in place.

Q: Where can LEDs be placed in the prop? A: LEDs can be placed in three main areas: two signature LEDs in the rotary mechanism, two red LEDs on top of the grip, and two to three LEDs (or a laser) in the front pod.

Q: How are the electronics powered? A: The electronic components, including LEDs, can be powered from the magazine.

Q: Is the front laser housing game-accurate? A: The front laser housing is designed to accommodate a 12mm laser, which is not entirely true to the game but is included for aesthetic appeal.

Q: Are there different versions of the main frame or rotary parts? A: Yes, the main frame has three versions (for the side details), and the rotary part has two versions (for text orientation).
