Parametric Luggage & Bag Tag - Text-Free Patterns (3 Presets)

A pattern band instead of a name

Identify a bag by geometry: raised eight-point stars, raised nested diamonds, or a row of real see-through diamond openings. The upper field stays blank for a sticker or marker. No CAD lettering is included.

These are CAD-checked prototypes, not physically print-tested products. No strength or load rating is claimed. Render colours are illustrative, not a multi-material specification. A visual marker is not a replacement for contact information when needed.

Three live-tested presets

• tag_std: 55 × 86 mm, R6 corners; 2.40 mm body / 3.68 mm overall; four raised eight-point stars with nested cores; 6.5 mm strap hole, centre 9.5 mm from top.

• tag_mini: 40 × 64 mm, R5; 2.20 / 3.32 mm; three raised nested diamonds; 5 mm hole, centre 7.5 mm from top.

• tag_bold: 60 × 96 mm, R7; 3.00 / 3.90 mm; four pierced diamond through-holes; 7 mm hole, centre 10.5 mm from top.

All have a raised border, strap-hole collar, and two raised rules framing the band. The blank field is flat, not a card sleeve.

Native TrueGeometry, no Boolean cuts or unions

The body and relief use native /sm_part profiles. The collar uses a sketch and /revolve. Two centre-line head halves with semicircular notches leave the strap opening. Two interlocking zig-zag body shells leave the bold tag's diamond openings; nothing is subtracted.

Closed shells overlap by 0.2 mm, or raised details sit 0.15 mm into the body. They are not unioned. The slicer must merge their printable volume correctly.

Customize with the command expander

tag_recipe.py.txt writes native Playground commands; it does not build geometry outside Playground. Rename it to tag_recipe.py to run locally.

Adjust width 35–90 mm, height 50–130, corner radius 3–12 (at most width/4), body 1.6–5, border 1.2–4, hole diameter 4–10, hole inset, pattern, count 3–8, band height 8–22, and relief 0.5–1.5. Patterns: stars, diamonds, pierced.

The hole edge must clear the raised border by 0.8 mm. These are generator limits, not a certified design envelope: keep the hole in the head region and inspect every custom result. Only the three presets were live-tested. Their generated commands reproduce the supplied literal recipes byte-for-byte.

Build and export

Open https://www.truegeometry.com/CoreWebGLTG/KBEAgentHTTP.html in an empty scene. Open Script, paste a complete recipe, and use Run, not Clean & Run. Inspect the geometry, answer the feedback prompt, then use STL in the bottom bar. Reload first if an old scene remains.

Slicing and validation

• Y-up export: rotate +90° about X so thickness becomes Z. Print flat, relief side up; confirm the orientation visually.

• Use a slicer configuration that merges overlapping shells. Preview the body, collar, first layers, and pierced struts before printing.

• Raised rules are 1.0 mm wide; larger nozzles may lose small nested cores.

• Pierced struts are roughly one third of the motif pitch at mid-height. No physical strength test was done.

• Check strap clearance. No material, infill, or load rating has been physically validated.

Export checks reported every shell closed, whole mesh watertight, consistent winding, zero degenerate triangles, and exact nominal bounds. Standard: 16 shells / 1,500 triangles. Mini: 14 / 1,092. Bold: 9 / 1,104. Mesh checks do not establish print quality or attachment strength.

Limits

No text or card-sleeve variant. A waves pattern was removed after export produced stray, unwelded triangles. Only the three presets ship. New sizes, motif counts, and festival reskins need fresh export and checks.

Files

Three STLs, three full native recipe text files, README, command expander, three mesh-check reports (the README calls them .json; Printables does not accept .json, so they are uploaded as .json.txt - rename after download), and the How-to-Run-a-Script PDF guide. Read the README before slicing. Recipes are attached in full rather than shortened in this description.
