SKÅDIS Infinite (Lightweight & Reinforced Structural Enhancement)

🔩 SKÅDIS Infinite Pegboard | Material-Saving Structural Reinforcement

📌 Model Introduction

This model is an infinitely modular pegboard for the IKEA SKÅDIS system, which can be extended horizontally and vertically according to wall requirements.
The core design focuses on material saving and reduced printing time, reinforcing rigidity through structural engineering, making it especially suitable for tool walls, workshops, and 3D printing storage.

The original Inventor (.ipt) file is also provided, allowing users to modify and customize it as needed.

🔧 Structural Design Highlights

• Redesigned back support structure to enhance overall rigidity and reduce bending when splicing large areas.
• Chamfers (Chamfer) added to critical positions to reduce stress concentration and improve print success rate.
• Hollowed weight-reduction design effectively reduces material consumption and printing time without compromising strength.
• New internal neutral axis linear reinforcement structure to effectively improve bending and shear stiffness.
• Modular design, allowing for infinite extension and splicing, suitable for various wall sizes.

⚙️ Parameters and Printing Recommendations

Main Infill

• 0.4 mm nozzle: 8%–20% (recommended 12%)
• 0.8 mm nozzle: 16%–24% (recommended 16%)

Infill Recommendations

• Recommended: Gyroid or Cubic
• Provides better structural rigidity with the same material usage compared to other infill methods.

Printing Time Reference

• 0.4 mm nozzle: approx. 2.5–4 hours
• 0.8 mm nozzle: approx. 1.2–2 hours

Structural Dimensions

• Main body thickness: 5 mm
• Rear support: 7 mm
• Countersink: outer diameter 8 mm / inner diameter 4.8 mm (M4)

Internal Linear Reinforcement

• Thickness: 0.4 mm (0.4 nozzle) / 0.8 mm (0.8 nozzle)
• Height: 2.2 mm
• Location: two layers at the exact center of the model height

🧠 Design Philosophy (Engineering Explanation)

This model deliberately does not use traditional inner and outer wall designs to reduce material consumption and printing time.
To compensate for the structural inadequacy caused by the absence of outer walls, 9 support points are added to the back, and linear reinforcement layers are incorporated at the neutral axis, effectively enhancing shear and bending stiffness.

This design achieves a good balance between material efficiency, printing speed, and actual rigidity, making it suitable for large-area and long-term SKÅDIS systems.

🔩 SKÅDIS Infinite Pegboard | Lightweight Structural Engineering Edition

📌 Description

This model is an infinite modular pegboard compatible with the IKEA SKÅDIS system, designed for horizontal and vertical expansion based on wall size.
The core focus is material efficiency and reduced print time, while maintaining sufficient rigidity through structural engineering improvements.

Ideal for tool walls, workshops, and 3D printing storage systems.
The original Inventor (.ipt) file is included for users who want to modify or customize the model.

🔧 Structural Features

• Redesigned rear support structure to improve overall stiffness and reduce bending on large panels.
• Chamfered critical edges to reduce stress concentration and improve print reliability.
• Weight-reduction cutouts to minimize material usage without sacrificing strength.
• Mid-plane straight reinforcement layers added at the neutral axis to enhance bending and shear stiffness.
• Fully modular design allowing infinite expansion.

⚙️ Printing & Slicer Recommendations

Main Infill

• 0.4 mm nozzle: 8%–20% (recommended 12%)
• 0.8 mm nozzle: 16%–24% (recommended 16%)

Recommended Infill Patterns

• Gyroid or Cubic
• Compared to Lines, Grid, or Honeycomb, these provide higher structural stiffness with less material in wall-less designs.

Estimated Print Time

• 0.4 mm nozzle: ~2.5–4 hours
• 0.8 mm nozzle: ~1.2–2 hours

Key Dimensions

• Main body thickness: 5 mm
• Rear support thickness: 7 mm
• Countersink: 8 mm outer / 4.8 mm inner (M4)

Internal Straight Reinforcement

• Thickness: 0.4 mm (0.4 nozzle) / 0.8 mm (0.8 nozzle)
• Height: 2.2 mm
• Location: two layers at the vertical center of the model

🧠 Design Philosophy (Engineering Perspective)

To reduce material usage and print time, this model intentionally avoids traditional inner and outer walls.
Structural rigidity is restored through rear support points and straight reinforcement layers placed near the neutral axis, significantly improving shear and bending resistance.

This design achieves an excellent balance between material efficiency, print speed, and real-world stiffness, making it well-suited for large-scale and long-term SKÅDIS applications.
