3d-print-designerlisted

Designs and generates parametric, FDM-print-optimized OpenSCAD (.scad) models — selects material (PLA/PETG/ABS) and optimizes for print orientation, layer adhesion, and structural strength. Triggers: "create a 3D model", "design a part", "make an OpenSCAD/.scad file", "design a bracket/enclosure/gear/mount", "something for 3D printing", or mentions CAD, STL, 3MF, FDM, filament, or printable assemblies.

# 3D Print Designer Design and generate parametric, FDM-print-optimized OpenSCAD (.scad) models. ## Step 0: Printer Configuration (always do this first) Ask the user what 3D printer they're using. Printer specs constrain build volume, material options, minimum feature sizes, and tolerances. See [printer-configuration.md](printer-configuration.md) — MANDATORY READ before any design work. It has the full workflow for identifying printer specs (auto from make/model via [printer-profiles.md](printer-profiles.md), or manual fallback) and how they affect design parameters. ## Step 1: Material Selection Determine the target material, **filtered by the printer's capabilities** (from Step 0). Warn the user if their printer can't handle the requested material and suggest alternatives. If the user hasn't specified a material, ask or recommend one: | Use Case | Recommended | Why | |----------|-------------|-----| | Prototypes, visual models, fine detail | **PLA** | Best overhangs, dimensional accuracy, easy to print | | Functional/mechanical parts, snap-fits | **PETG** | Ductile, impact-resistant, good layer adhesion | | Outdoor use, heat exposure | **PETG** | Higher Tg (75-85C vs 55-65C), moderate UV resistance | | Living hinges, flexible features | **PETG** | 200-300% elongation vs PLA's 2.5-6% | | High heat resistance (up to 80C) | **ABS** | Tg 100-110C, best heat resistance of common filaments | | Impact-resistant parts | **ABS** | 3-5x impact strength of PLA | | Smooth surfa
