TheOptiForge Cyber-Claw | Adjustable GPU Anti-Sag Bracket

🦾 CyberClaw GPU Bracket | Anti-Sag System

Stop the sag. Upgrade your build. Today's massive graphics cards demand massive support. The CyberClaw is designed from the ground up to be the ultimate fusion of industrial "Cyberpunk" aesthetics and brute mechanical strength. Forget boring, smooth plastic tubes—this is a GPU bracket built to be shown off.

Engineered with FDM-optimized angles, it can be printed 100% support-free, right on the build plate, though I recommend supports for the "Claw" as it needs to be printed at an angle.

⚙ Choose Your Mechanism (3 Variants)

Every PC build is unique, and so are your preferences for adjustment. The CyberClaw package includes three distinct height-adjustment mechanisms. Choose the one that fits your style:

1. The Pillar (Direct Screw)

The cleanest and most direct solution. The base features a massive, internal "Mega-Thread", and the top claw screws directly into it.

• Advantage: Minimalist design with the fewest possible parts.

• Use Case: Perfect for light to medium-weight graphics cards. Screw it up until it meets the card, and leave it.

2. The Lock-Nut (Screw & Nut)

Inspired by heavy industrial machinery. This variant uses a coarse threaded rod with a separate, machined Lock-Nut.

• Advantage: Extreme stability. Once you've found the correct height, tighten the nut down against the base. This completely locks the threads and eliminates any chance of vibrations from PC fans causing the bracket to creep or lower over time.

• Use Case: A must-have for the heaviest flagship cards (RTX 4080/4090/RX 7900 XTX).

3. The Tactical Wedge (Sliding Mechanism)

For those who want to avoid visible threads entirely. This utilizes a two-part sliding mechanism where an angled wedge is pushed horizontally to raise the top claw vertically.

• Advantage: Stepless, smooth adjustment with an incredibly clean and aggressive profile. The downward pressure from the graphics card automatically locks the wedge in place via friction.

• Use Case: Fast installation and a unique visual statement in your case.

🖨 Recommended Print Settings (The Forge Standard)

For the CyberClaw to withstand the weight of a heavy GPU over several years, it is critical to build strength in the walls, not just the infill.

• Layer Height: 0.20 mm (Provides perfect tolerance for the threads).

• Walls/Perimeters: Minimum 5-6 walls. This is the secret behind indestructible 3D-printed threads.

• Infill: 25% Gyroid or Cubic.

• Supports: NO. All parts are printed standing up and are DFM-optimized with maximum 45-degree overhangs.

• Material: PETG, ASA, or ABS is highly recommended. PLA works perfectly for fit-testing, but since PC cases regularly reach 40-50°C during gaming, PLA under sustained load will gradually soften and "creep" (sag) over time.

🛠 Assembly Instructions

1. Print the parts corresponding to your chosen system (Pillar, Lock-Nut, or Wedge).

2. Place the base at the bottom of your PC case (pro-tip: use a drop of double-sided tape or a small rubber pad underneath the base if you have a smooth metal PSU shroud).

3. Position the "Claw" under the solid frame or heatsink of your graphics card. Important: Ensure it is not resting against the fans!

4. Adjust the height until it perfectly supports the weight of the card, and lock it in place.
