Parts gallery

Every STL in hardware/stl, each in its own 3D viewer, as exported for printing (Z up = away from the bed). Bounding box, volume and triangle count are measured from the meshes when the site is built. Material and orientation follow ASSEMBLY.md and the print plan; print settings are starting points, not values tested on this design.

Fit is unverified. The knob, rod and clip dimensions behind these parts are estimated from photo, not caliper. Print the clip rail and a cup + liner as fit tests before anything else.
