Curved Wing Section - Printable Surface Study

OVERVIEW - ONE WING SEGMENT
This printable surface study contains one curved wing-section STL and a normalized OBJ component-viewing copy. The supplied STL retains 4,762 triangle records; the separate normalized OBJ viewing copy has 4,730 faces. Its cut ends, small projecting tabs and narrow slit are part of the inspected section. This is not a complete aircraft, a complete wing or a complete RC kit. No missing airframe, tail, landing gear, motor, propeller or additional wing sections have been reconstructed or added.

DOWNLOAD CONTENTS
Each complete ZIP retains the supplied numerical STL geometry, the OBJ viewing copy, four technical/reference JPG images, an eight-page English preparation and context PDF, the current presentation image, an English text guide, a current integrity manifest and CC0 information. Identical repeated source resources are stored once in each complete ZIP. Earlier identifying filenames, source paths, export labels and private preparation records are absent from the public package. The file inventory lists only current independent neutral names, sizes and hashes.

DOCUMENTATION AND CONTEXT
The PDF explains preparation of the included section and retains eight technical illustration regions from the wider-project documentation: the exploded project reference, wing joints, fuselage relationships, servo, motor, alignment and balance, landing gear and paint schemes. English prose replaces the earlier branded Spanish general manual. Full-aircraft dimensions, hardware values and assembly relationships are marked as contextual rather than included components. The wider project discusses an 840 mm span and 590 mm length; those numbers do not establish this isolated section's dimensions or scale. Images and diagrams do not supply the rest of the aircraft, downloadable videos, slicer projects or ready-to-run machine files.

GEOMETRY AND PREPARATION
STL facet records and OBJ numeric coordinates, connectivity, normals and other geometric statements retain their supplied values. The OBJ is a component viewing copy; use the supplied full-resolution STL for dimensional checks and preparation. Confirm units and measure the actual section before printing. Inspect the curved skin, cut ends, tabs, narrow openings, disconnected surfaces and any non-manifold edges. A visually closed surface or an attractive illustration does not certify printable wall thickness or fit to another assembly. Keep repairs, thickening and changes on a working copy.

PRINTING ADVICE - UNTESTED
Choose orientation and supports after checking the section in a slicer. Avoid trapping supports inside a narrow opening, crushing a thin skin or loading a projecting tab during removal. Test a small edge or tab before printing the entire section. The historical wider-project notes mention PLA around 190 C and printer envelopes of 195 x 195 x 185 mm and 200 x 200 x 180 mm; these are contextual notes, not verified settings or a required bed size for this section. Material, nozzle, layer height, temperatures and cooling must match the actual printer, filament and measured geometry. No physical print or mechanical fit has been verified by the publisher.

Untested source geometry. Confirm slicer units, manifoldness, intersecting surfaces and fine-feature thickness. The upright display OBJ is normalized for visualization; use full-resolution source geometry in the corrected package for fabrication checks. No verified physical scale, print settings, assembly fit or flight capability is claimed.
