A sixty-eight-file modular truss collection supplied under a QUADRO finish-gate source name. Every original STL was visually inspected in six geometry contact sheets. The meshes comprise ten straight lattice modules, four corner lattice modules, one shorter open truss module, forty-eight stepped hollow tube connectors, four cylindrical corner pins and one post base plate.

All sixty-eight original files are preserved unchanged and renamed in English. Their SHA-256 contents differ; repeated-looking components have different stored coordinates and must not be assumed byte-identical. The supplied source coordinates form a disassembled layout, not a verified assembled finish arch. File counts describe mesh contents rather than a tested bill of materials.

The base plate has post-like supports and a central opening. Connector and pin fit, intended orientations, module alignment, stability, assembled dimensions and required print quantities have not been established. No verified scale is supplied. No banner, electronic timer, lights, sensors, fasteners or additional hardware is included.

The displayed arrangement is illustrative and cannot establish a working structure or tested joints. MESHOPIA has not physically printed or assembled this collection. No material, load capacity, print settings or tested assembly instructions are claimed.

The new cover renders supplied truss, base, corner and connector meshes in Blender as an inferred static arch display over a locally generated ComfyUI workshop background. Selected source meshes are repeated to illustrate two posts and a top beam; connector examples remain beside the arch. Corner rotations, repetitions and joints are presentation assumptions, not verified assembly instructions or a tested bill of materials. Open tube ends and interfaces require independent fit checks.
