Capsule tools
2026-09-11

This page generates millimetre STL models in your browser. The preview uses the
same STL buffers as the download. No model generation server is required.

Geometry source: model.js. Rendering: viewer.js. Interface: app.js.
The model follows the capsule holder and funnel designed and printed in this project.
The original 100 mg-labelled product is preserved as its own design preset;
its capsule size has not been identified from that weight label.

Reference body diameters and cut lengths:

Preset adjustment ranges are design limits of this tool, not manufacturer tolerances.

STL files are geometric prototypes. A regenerated mesh does not establish
physical fit, powder flow, or suitability of a printed contact surface.

Revision 3: preset labels include millimetres. Hole depth is directly
adjustable. Capsule body length is a preset reference used for the illustration
and depth bounds. In custom mode, users enter body diameter (4.5–12 mm)
and body length (8–32 mm); hole depth remains a separate parameter. Funnel mouth, stem length and height
scale with capsule diameter; mouth can be adjusted from 80 to 120 percent of
that diameter-derived value. STL exports have Z min = 0, holder pockets up and
funnel mouth down. The print orientation view uses the exported orientation.

Camera rotation and relative zoom persist when geometry is regenerated.

Run deploy/build-capsule-feed.py to synchronize this article with feed.xml
and the root listing. The existing RSS GUID and publication date are preserved.

Changed JS imports, worker URLs, stylesheet and image references use the
20260911-r3 version query to bypass the origin's immutable asset cache.
Bump these references when publishing future revisions of those assets.
