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
# Two-Stage Herringbone Planetary Reducer Design ## Part Analysis - Product: compact coaxial two-stage planetary reducer with input and output flanges. - Envelope target: maximum outside diameter `50 mm`, total height `30 mm` along the reducer axis. - Power path: input flange -> input shaft -> stage 1 sun -> stage 1 carrier/intermediate shaft -> stage 2 sun -> stage 2 carrier/output shaft -> output flange. - Gear type: all active mesh gears are herringbone gears to cancel axial thrust and keep the stacked reducer compact. - Standard parts: herringbone gears, herringbone ring gears, and radial ball bearings come from `simplecadapi.std.gear` and `simplecadapi.std.bearing`. - Custom solids: housing sleeve, shafts, carriers, and flanges are integrated SimpleCAD solids built from cylinders, boxes, booleans, and tags. ## Structure Analysis - Stage 1 uses `S1=12`, `P1=18`, `R1=48` teeth, giving fixed-ring planetary reduction `1 + R1 / S1 = 5:1`. - Stage 2 uses `S2=12`, `P2=12`, `R2=36` teeth, giving fixed-ring planetary reduction `1 + R2 / S2 = 4:1`. - Total reduction is `5 * 4 = 20:1`. …

How to install
mdr add nijingzhe/simplecadapi/examples/compact_two_stage_planetary_reducer/DESIGN.md@sha256:3a22ba6b25e59442The line at the top of this page pins the label git:20261002.49f142a, 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.
