Toa Payoh Dragon
A small, soft-edged interpretation of Singapore’s Toa Payoh Dragon Playground, made with puffy hoops, a colourful winding body and chunky slide supports.

Print status
v03 is a fit-test candidate. Digital mesh, clearance, insertion-path and offline slicing checks passed. Physical printing, fit and support removal have not been tested. Print the representative joints before the whole model, and use matching v03 parts.
Prepared for a Bambu Lab X1 Carbon with a 0.4 mm nozzle and PLA. Six colours print separately; no AMS is required. The kit includes 94 model parts, 29 fit samples and 9 optional assembly cradles across 19 layouts. Some pieces require supports. Use the supplied orientations at 100% scale.
The kit ZIP is the existing validated artifact; publication does not regenerate its geometry. SHA-256: 614826200cf5f60f3b15884abf88248671c4207a51d37d3097c312009f65d972.

Shape and source
The model captures the playground’s gist rather than reproducing it to survey accuracy. The printable version has 15 closed puffy hoops and three open tail rungs, a photo-informed head and slides, and a split display base. The playground length is approximately 230 mm, excluding the base.
Design direction distinguishes the approved concept, the visual v06 model and the printable v03 assembly. Reference records retain photograph sources and attribution; photographs are not bundled.
Repository contents
This public checkout contains the current source, required source meshes, editable Blender scenes, v03 kit, selected renders and its digital evidence. It omits superseded print kits, procedural drafts, duplicate render galleries, downloaded reference photos, Python environments, Blender backups and transient scratch files. The original authoring folder retains that history locally.
The retained exports/dragon-pla-kit/work/source-v06/ directory is an input to the current print library despite its older parent name. The v03 work/assembly/ meshes and slicing records support the existing validators and packager. Do not remove either as disposable cache. Logs may contain paths from the authoring machine; they are historical evidence rather than portable instructions.
Verification and publication
Run python3 scripts/check_documentation.py and python3 scripts/check_publication.py. The documentation gate pins EngineeringRules 0.1.11 at 3e42da0e724fe54585cc3cdd9009c749f7ba24d9; see the toolchain guide for its separate installation requirements. The publication check verifies local links, Python syntax, kit checksums and website boundaries without generating CAD.
GitHub Pages publishes only site/ after changes land on main. Pull requests receive the publication check and a separate engineering review. CAD and browser checks establish different evidence; neither proves a successful physical print.
