# Burr Example Gallery
These examples are small printable parts, not abstract fixtures. Each `design.py`
generates:
- a STEP artifact
- `burr-design-data.json`
- a Burr receipt from `burr check`
Run:
```bash
npm run check:gallery
```
The generated CAD artifacts are ignored by git. The source files are the stable
CAD contract; the receipts are regenerated to prove that Burr can connect the
declared mechanical intent to exported STEP geometry.
## Parts
- `shaft-bearing-bracket`: bearing seat plus loaded M3 side mounts.
- `slotted-motor-plate`: adjustable straight slot plus counterbored fasteners.
- `electronics-standoff-deck`: heat-set insert pockets plus clearance holes.
- `dense-random-hole-plate`: mechanical mount holes plus many cosmetic holes
checked by a count rule.
- `t-slot-linear-slider`: two-part captured slider with declared clearance
windows and capture lips.
- `dense-random-hole-plate-too-few-reliefs`: negative fixture for feature-count
rules.
- `t-slot-linear-slider-loose-clearance`: negative fixture for numeric clearance
rules.
