build_model
ChatGPTPartwright is a registry for finished models: it rebuilds and validates submitted CadQuery source, then saves each successful build as an immutable version with a preview for the user, downloads, and print quotes. When a design needs iteration, do it in your own code sandbox with CadQuery 2.8.0, however you see fit. A simple shape can be written and submitted in one go. Submit only finished, self-contained source with build_model, never experiments: each successful build becomes a saved version. The user can set how many of each part to print at checkout, so extra copies for printing do not need to be added to the model. For designs intended for printing, use Slant’s published standard build volume of 220 x 220 x 220 mm as the planning limit for each individual part in a suitable printing orientation, regardless of selected material/color. Consider whether rotating the part allows it to fit; an oversized bounding box in the current model orientation alone does not prove that the part is too large. Do not assume either automatic reorientation by the supplier or a fixed print orientation. The assembled model may be larger. Do not silently scale down user-requested dimensions. If a part cannot fit this envelope in a suitable printing orientation, propose splitting it into separately printable parts with suitable joints, or ask whether resizing is acceptable. A part fitting this envelope is not guaranteed printable; the supplier quote remains authoritative.Every printable part must have an explicit available filamentId from list_print_filaments before building. If the user has not specified a material or colour, choose a fitting available option yourself without routinely asking. Honor explicit requests; if unavailable, ask the user rather than substitute. cq.Color does not select a print filament and cannot replace filamentId. Reference geometry always uses the fixed translucent reference style; supplied colours and filament metadata cannot customize it. Queue a new model or immutable version from Python CadQuery source. Numeric inputs are available only through the Python parameters dictionary, not injected as standalone variables. For parameters={"width":40}, bind width = parameters["width"] or width = parameters.get("width", 40) before using width. Keep supplied dimensions parameterized rather than hardcoding them. Assign the final solid Workplane, Shape, or named Assembly to result; a variable named model alone is not an output. Mark existing objects, fitting guides, or other preview-only geometry with assembly metadata={"role":"reference"}. Reference parts stay visible in the preview but are excluded from STEP/STL downloads, print estimates, and checkout. All other parts default to role="printable". A reference subassembly makes all its children reference-only. Keep at least one printable part; use distinct partIds for reference and printable geometry. Reference parts do not need filament selections. Hiding a part in the viewer does not change whether it prints. Each printable part is printed individually in one material/color. Do not assume multicolor printing or automatic bonding between touching parts. Design the intended relationship between parts: loose, resting, removable, or attached. Where attachment is needed, include a suitable attachment method and explain any required glue or hardware. Account for appropriate clearances wherever parts fit together. Reuse the same id UUID only when resending an unchanged request after a transport failure; it returns the original job, including a failed job, without executing again. Use a new UUID for corrected source, changed inputs, or another build attempt. After a failed build, retain its modelId and the unchanged expectedParentId. For a new model omit modelId and use null expectedParentId; for edits supply the latest version ID. For colors, call list_print_filaments and set metadata={"partId":"lid","filamentId":"<catalog ID>"} on each new assembly part. For overrides validated before queueing, pass filamentSelections. Use definition:lid only when metadata explicitly sets…
