Project Brief: Slim, Stable Monitor Riser for Gigabyte Aorus FV43U

Goal

Design and build two compact risers (one per pair of monitor feet: left and right) to raise a Gigabyte Aorus FV43U monitor by 190 mm (19 cm), allowing a laptop to sit open in front of the screen, while remaining stable on a standing desk that exhibits some wobble.

Key constraints

• Minimal footprint (significantly less than current 380 mm depth)
• Very high lateral stability
• No permanent modification of the monitor
• Clean, furniture-grade appearance
• Buildable with woodworking tools + consumer 3D printer

Monitor & Desk Context

• Monitor weight (with stand): ~10 kg total (~5 kg per foot)
• Stand type: two independent metal feet
• Desk depth: 900 mm
• Desk type: height-adjustable standing desk (prone to small lateral oscillations)
• Primary instability risk: micro-movement and walking, not static tipping

Final Riser Geometry (Per Side — Paired Feet)

Overall Dimensions

• Height: 190 mm (19 cm, fixed)
• Width (left–right): 190 mm
• Depth (front–back): 300 mm (30 cm) — combined riser depth for each paired-foot riser

This footprint provides strong resistance to dynamic sway for each paired-foot riser; depth trade-offs prioritize supporting both feet per riser while keeping the riser compact compared to the original full stand depth.

Structural Layout

Layered vertical stack (bottom → top):

1. Bottom damping layer

   • 3–5 mm rubber or cork–rubber composite
   • Shore A ≈ 50–60
   • Covers ≥80% of base area

2. Wooden structural core

   • Height: 165 mm
   • Width: 190 mm
   • Depth: 300 mm
   • Material:
     • Hardwood (oak, beech, maple), or
     • Laminated birch plywood
   • Chamfered edges (~5 mm) to reduce visual bulk

3. 3D-printed locking cradle

   • Height: 20 mm
   • Width: ~160 mm (contour to pair spacing)
   • Depth: ~280 mm (to accommodate paired feet within the combined riser)
   • Material: PLA+ (non-structural)
   • Mechanically bonded to wood (VHB tape or screws from below)

Total height: 190 mm (19 cm)

Locking Mechanism (Critical Feature)

Type

Shallow mechanical foot pocket (parking-curb style)

Geometry

• Pocket depth: 4–5 mm
• Wall thickness: ≥4 mm
• Clearance: +0.5 mm per side relative to monitor foot
• Rear stop: 6 mm vertical lip
• Bottom of pocket: flat (monitor foot rests on solid surface)

Function

• Prevents lateral sliding in all directions
• Blocks forward/backward movement during desk oscillation
• Does not trap the foot vertically (lift-off removal remains possible)
• Relies on geometry, not friction alone

3D Printing Parameters (PLA+)

• Print orientation: flat on build plate
• Walls: 4–5 perimeters
• Infill: 25–30% (gyroid or cubic)
• Layer height: 0.2 mm
• Internal fillets: 1–2 mm at pocket corners

PLA+ is acceptable because it carries no bending load and only experiences compression and contact forces.

Stability Strategy (Standing Desk Optimized)

• Wide stance (190 mm) resists lateral acceleration
• Reduced lever arm from targeted depth (300 mm per combined riser) balances compactness and paired-foot support to minimize oscillation leverage
• Bottom rubber layer damps desk motion and prevents “walking”
• Mechanical foot lock eliminates slow creep over time

Material Choice Rationale

• Wood (preferred):
  • High damping
  • Light enough for standing desk motors
  • Easy to shape and iterate
• Concrete: explicitly avoided due to poor dynamic behavior, high mass, and desk wear risk

Status

This design is considered:

• Mechanically safe
• Optimized for minimal bulk
• Ready for CAD modeling and fabrication
• Suitable for further refinement (visual tapering, material finish, cradle contouring)

Possible Next Iterations

• CAD-ready dimensioned drawings
• Exact cradle contour matching the FV43U foot
• Further depth reduction trade-off analysis
• Visual slimming (tapers, shadow grooves)
• STL generation for the cradle
