SCAD Library NopSCADlib Skill

Use NopSCADlib when include <NopSCADlib/core.scad> is listed in the runtime prompt and the requested part benefits from real-world electronics or mechanical components.

Import

Start with the core include only when available:

include <NopSCADlib/core.scad>

Add narrower NopSCADlib vitamins/... or printed/... includes only when the exact module and path are known. Prefer simple printable geometry if uncertain.

Best Uses

• Use for electronics enclosures, project boxes, PCB holders, fan mounts, Raspberry Pi/Arduino-style board clearances, screw bosses, inserts, spacers, and assembly-aware designs.
• Use NopSCADlib as reference vocabulary for real components: boards, screws, bearings, fans, connectors, switches, cable glands, rails, rods, and panels.
• Prefer generated printable carrier geometry around real components rather than modeling every electronic detail.
• Keep non-printable purchased parts visually useful but clearly separate from the printed part when rendered.

Generation Pattern

Keep the printable part self-contained and parameterized. Use real component placeholders only when they improve fit reasoning:

include <NopSCADlib/core.scad>

/* [Enclosure] */
width = 90;          // min: 40 max: 220 step: 1
depth = 60;          // min: 30 max: 180 step: 1
height = 28;         // min: 12 max: 100 step: 1
wall_thickness = 2;  // min: 1.2 max: 6 step: 0.2
boss_diameter = 8;   // min: 4 max: 16 step: 0.5
screw_diameter = 3;  // min: 2 max: 5 step: 0.1

module printable_enclosure() {
  difference() {
    cube([width, depth, height], center=true);
    translate([0, 0, wall_thickness])
      cube([width - 2*wall_thickness, depth - 2*wall_thickness, height], center=true);
  }
}

printable_enclosure();

Quality Rules

• Model clearances explicitly: board clearance, screw clearance, cable clearance, lid/body fit clearance.
• Keep screw bosses connected to walls or ribs.
• Add ribs, chamfers, and strain relief where loads enter the enclosure.
• Do not let visual component placeholders become required printable geometry unless requested.
• Avoid overfitting to a named board unless exact dimensions are supplied.

Avoid

• Do not include broad NopSCADlib files speculatively.
• Do not invent module names or type constants.
• Do not copy NopSCADlib source into generated SCAD.
• Do not generate BOM/project automation output inside scad_source; keep output focused on renderable OpenSCAD.
