lab-hardware-cad SKILL.md skillA

lab-hardware-cad from k-dense-ai/scientific-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add k-dense-ai/scientific-agent-skills/lab-hardware-cad@v1.5

Pins v1.5 in mdr.lock. Pin the fingerprint instead.

Designs custom laboratory hardware as parametric build123d models and exports fabrication artifacts as STEP, STL, and DXF files - microfluidic chips and molds, optomechanical mounts and breadboard adapters, cuvette and microplate holders, tube racks, animal-behavior rigs, and 3D-printed instrument fixtures. Use when a research task needs a physical part that must mate with standardized labware, an optical table, a cage system, or a printer, CNC, or laser process.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Lab Hardware CAD

Design physical research hardware as **parametric Python source**, export STEP as the
authoritative artifact, and verify the result both numerically and visually before anything
is fabricated.

The hard part of lab hardware is almost never the geometry. It is that the part must mate with
equipment whose dimensions are fixed by a published standard or a vendor drawing. A holder that
is 0.5 mm too wide does not fit the plate reader; a channel with the wrong aspect ratio collapses
during bonding; a mount whose bolt pattern is 25.4 mm instead of 25.0 mm will not reach the
optical table. This skill exists to keep those numbers correct and checked.

## When to use

Use for any request to design, model, or fabricate a physical part for a lab: chip, mold, mount,
adapter, holder, rack, bracket, enclosure, jig, fixture, arena, or maze. Also use to inspect or
modify an existing STEP file.

Do **not** use for finite-element analysis, computational fluid dynamics, molecular structure,
or scientific plotting. Those are different skills.

## Setup

```bash
uv venv --python 3.12 .venv-labcad
uv pip install --python .venv-labcad/bin/python "build123d==0.13.0" "matplotlib>=3.8"

How to install

The exact contents, by fingerprint
mdr add k-dense-ai/scientific-agent-skills/lab-hardware-cad@sha256:d3e9c67c3f08bfd7

The line at the top of this page pins the label v1.5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
