Copperfen Steamworks - 4 Fantasy Scenery Models STL + CAD

Build a fantasy steamworks yard with four detailed fixed scenery assemblies: Rivetwall Vertical Boiler, Twin-Cylinder Steam Engine, Rocker-Beam Flywheel Pump and Copperfen Tracked Hauler. Includes 4 original STL meshes, 4 matching standalone editable OpenSCAD sources, 8 front/rear actual mesh renders, illustrated HTML catalog, dimensions, check reports and a personal-use license. Complete digital collection: $4.

Rivetwall Vertical Boiler — Closed vertical boiler sculpture with domed crown, three raised shell collars, four rows of twelve radial rivets, closed fire-door relief, handle, two backed gauges, capped stack, joined return pipe, flanges, fixed handwheel and a nine-rung access ladder with upper mounting straps. Decorative machine only.

Twin-Cylinder Steam Engine — Paired closed horizontal cylinders, six raised flange collars, sixteen end-bolt studs, thick fixed piston-like rods, central supported axle, two open-spoke toothed flywheels, joined supply pipes, capped receiver, fixed handwheel and a three-gauge backed control panel. Every part is fixed.

Rocker-Beam Flywheel Pump — Two upright closed cylinders with six flange collars, joined outer pipes, fixed exposed piston-like rods and tilted rocker beam, supported shaft, twenty-tooth open-spoke flywheel, fixed handwheel, gauge panel and a blank front plaque. No pumping or working controls.

Copperfen Tracked Hauler — Original unbranded closed steam hauler with two solid tracked undercarriages, raised tread blocks, ten wheel-like reliefs, banded horizontal boiler, eight cap-bolt studs, capped stack, joined side pipe, gauge, open-sided fixed cab frame, roof, rear window opening, seat, handwheel and closed rear cargo box with fixed coal-like lumps. Fixed decorative vehicle; no moving tracks or propulsion.Free preview catalog: browse the actual models before buying. The preview download contains images and inventory only, no STL or CAD files.

All four STLs passed watertight, consistent winding, positive volume, single connected body, flat Z=0 base and nonempty cross-section checks every 0.4 mm. All four exact CAD sources independently compiled in OpenSCAD with at most 0.02 mm bounds, 0.5% relative volume and 1% symmetric-difference volume error. All four exact STLs sliced in OrcaSlicer 2.4.2 using K1 SE 0.4 mm / Generic PLA / 0.16 mm layers / 3 walls / 15% infill / normal automatic supports aligned to model layers, base down. Every named slicer layer has extrusion; checked extrusion paths remain within that profile bed and height. Reports and hashes are included.

Images render the actual delivered meshes. Physical printing, support removal, fine-detail survival, strength and fit remain untested. Import STLs in millimeters, review your own slices and make trial prints at supplied dimensions before scaling down. Automatic supports were enabled in the recorded checks; customer G-code and pre-supported files are not included. Each model is a single fixed decorative assembly on a paving base. Boiler shells, cylinder forms, cargo boxes, gauge faces and stacks are closed; gears, piston-like rods, treads, handwheels, controls and all other parts are permanently fixed. Flywheels have open spaces between their thick spokes. The hauler cab has open sides and a rear window opening; no guaranteed figure clearance or common figure scale. No moving mechanisms, calibration, propulsion, pressure, steam, fuel, fire, heat, electrical, lifting or working-light function. Digital scenery files only: no physical goods, painted finish, textures or game rules. Views are fitted separately; full dimensions are included.
