🔵 Fully Parametric Round Spacer (OpenSCAD)

A clean, production-ready fully parametric round spacer designed for real-world 3D printing applications.

This is not just a basic cylinder with a hole — it includes fit tuning, chamfer control, and optional counterbore features to adapt to different mechanical needs.

Perfect for electronics, structural assemblies, robotics projects, enclosures, furniture builds, and general workshop use.

⚙️ Features

• Fully parametric OpenSCAD design
• Adjustable outer diameter
• Adjustable inner diameter
• Adjustable height
• Built-in tolerance control for precise bolt fit
• Optional chamfer (reduces elephant’s foot & improves finish)
• Optional counterbore
• Clean, reusable architecture

🧩 Ideal For

• M3 / M4 / M5 / M6 bolt spacing
• PCB standoffs
• Enclosure spacing
• Robotics assemblies
• DIY mechanical builds
• 3D printer mods

🖨 Recommended Print Settings (PLA – Bambu Lab A1 tested)

• 0.2mm layer height
• 3–4 walls
• 100% infill (for structural use)
• No supports required
• Hole tolerance:
  • +0.2 to +0.3mm for standard bolt clearance
  • -0.1mm for light press-fit

🛠 Why Parametric?

Most spacer models force you to scale the entire object, which distorts tolerances.

This design keeps:

• Hole fit independent
• Outer diameter independent
• Height independent
• Fit tuning separate from geometry

That means predictable mechanical results.
