Stl Renderer

Render publication-quality PNG views of any binary STL file — isometric (3-D perspective), top-down XY projection, and XZ cross-section at Y midpoint. All dimensions derived from the STL bounding box; nothing hardcoded. Optionally uploads to imgur and returns URLs. Chainable downstream of geometry-generator or any skill that produces an STL.

STL Renderer

Produces three views of any binary STL mesh:

View	Description
`isometric`	3-D perspective, elev=28° azim=−55°
`top`	XY top-down projection
`crosssection`	XZ slice at Y=midpoint (shows rib/fin profile)

Usage

# All three views, local PNGs
python3 {baseDir}/scripts/stl_renderer.py --stl /path/to/mesh.stl

# Subset of views
python3 {baseDir}/scripts/stl_renderer.py --stl mesh.stl --views isometric crosssection

# Custom output dir + imgur upload
python3 {baseDir}/scripts/stl_renderer.py \
  --stl mesh.stl \
  --out-dir /tmp/render \
  --upload-imgur

# High-res with YZ cross-section instead
python3 {baseDir}/scripts/stl_renderer.py \
  --stl mesh.stl --dpi 300 --slice-axis x
