What is print-in-place?

A design guide for 3D-printed mechanisms whose parts move relative to each other after printing, such as hinges, joints, snap fits, and articulated chains.

Use it when designing, modeling, or analyzing print-in-place mechanisms in tools such as Blender or OpenSCAD.

It explains the clearances, shapes, failure modes, and checks needed to make moving parts print and move correctly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00057	$0.00143
Opus 5.5	$0.00023	$0.00057
Sonnet 5.5	$0.00011	$0.00029
Haiku 4.5	$0.00006	$0.00014

Security

Grade A, and why

print-in-place scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

This skill is a Codex-specific shim. The full, agent-agnostic guidance is in docs/design/print-in-place.md — cardinal rule, clearances, mechanism patterns, LLM failure modes, validation checklist.

Read it before designing any moving-parts mechanism. The rules apply regardless of backend (Blender, OpenSCAD).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
