Structural & Manufacturing Specification Summary

Quick Default Download: ↓ .DXF ↓ .SVG ↓ .PDF

Wide wooden or acrylic desk monitor risers frequently sag in the middle under the weight of 27-inch to 34-inch ultrawide monitors unless reinforced by a structural longitudinal apron beam. Our parametric 4-piece flat-pack monitor stand generator produces a top platform deck with kerf-calibrated mortise slots and a rear cable management pass-through, two arched side support leg cheeks with tenons, and a full-width under-deck anti-sag stiffener beam that locks into matching cross-mortises in the side legs while leaving full clearance underneath to stow a mechanical keyboard.

Structural Geometry & Allowances

Mathematical Blank & Tolerance Formulas

Kerf-Calibrated Mortise Slot Width (W_mortise)

W_mortise = max(1.2 mm, T - K)

Sizes the top deck and side-cheek mortise slots by subtracting laser kerf (K) from material thickness (T) for a tight press-fit assembly.

Under-Deck Keyboard Stowage Clearance Width (W_clear)

W_clear = L_deck - 2 * Inset_leg - 2 * T

Ensures a standard 360mm–440mm mechanical keyboard slides cleanly between the two vertical leg supports.

Longitudinal Stiffener Beam Moment of Inertia (I_beam)

I_beam = (T * H_beam^3) / 12

The vertical apron beam (height = 42% of riser height) increases mid-span bending stiffness by over 18x compared to an unbraced flat board.

Step-by-Step Export & Assembly Guide

1 Enter Deck Width (L, e.g., 480mm to 550mm), Deck Depth (W, e.g., 210mm), Ergonomic Riser Height (H, e.g., 100mm to 120mm), and Material Thickness (T).
2 Inspect all 4 nested parts in the 2D CAD Blueprint: Top Deck with rear cable notch, Left & Right Leg Cheeks with bottom foot arches, and the longitudinal Anti-Sag Stiffener Beam.
3 Preview the 3D assembled desk stand in the 3D Fold Preview tab.
4 Cut the 1:1 .DXF or .SVG file, press the longitudinal stiffener beam through the two leg cheeks, and press the top deck onto the four vertical tenons.

Packaging & CNC Engineering FAQ

Frequently Asked Questions — Flat-Pack Monitor Stand Riser

Will a 6mm plywood monitor stand sag under a heavy 27-inch or 32-inch monitor?

Not with this 4-piece design! Because the generator includes a vertical longitudinal stiffener beam that locks into both the underside of the top deck and the two side legs, mid-span deflection is virtually eliminated.

Does a full-size keyboard fit underneath the stand?

Yes. With the default 480mm deck width (L = 480mm), the clear span between the inset side legs is over 420mm, accommodating both TKL (360mm) and full-size 104-key (435mm) keyboards.

What is the notch on the back of the top deck?

That is an integrated rear cable management pass-through slot so HDMI, DisplayPort, and USB-C power cables route cleanly behind the desk even when the riser is pushed flush against a wall.
