3D Print Preparation

Installation

1. 1
   Make sure Claude is on your device and in your terminal.

   Skills load from ~/.claude/skills/ when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then run claude in any terminal to verify.

   One-time setup

   Copy

   npm i -g @anthropic-ai/claude-code

   Already have it? Skip ahead.

2. 2
   Paste into Claude Code or into your terminal.

   Install

   Sign up to copy

   This downloads the skill into ~/.claude/skills/cad-3d-print-prep/SKILL.md.

3. 3
   Restart Claude Code.

   Quit and reopen Claude Code (or any other agent that loads from ~/.claude/skills/). New skills are picked up on startup.

4. 4
   Just ask Claude.

   Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.

Prefer to read the source first? Open on GitHub.

When Claude uses it

Prepare a 3D model for printing — pick orientation, plan supports, choose perimeters/infill/layer-height, predict failure modes, and emit slicer settings. Use when the user asks "how do I print this", "slicer settings for X", "what orientation", "will this work in PLA/PETG/ABS/resin", "should I support this", or hands you an STL/3MF and a printer/material. Covers FDM (PrusaSlicer, OrcaSlicer, Bambu Studio) and MSLA resin (Chitubox, Lychee).
