Tideglass Reef - 100 Underwater Scenery Models STL + CAD

Tideglass Reef is a collection of 100 stylized underwater scenery assemblies: four larger hero scenes plus 24 smaller prop families with four different layouts each. Nine folders cover reef ruins, coral gardens, reef floor, sunken stone, drowned shrines, wreck debris, cargo holds, pearl market and tide markers. These are 100 complete model assemblies, including family variants; views and CAD copies are not counted as extra models. Includes 100 STL meshes, 100 matching editable OpenSCAD sources, 200 actual mesh previews, numbered illustrated catalog, dimensions, check reports and personal-use license. Complete digital collection: $8.Browse the free preview catalog to see all 100 models before buying. The preview catalog contains images and inventory only, no model files.

All 100 delivered STLs passed closed watertight mesh, consistent winding, positive volume, one connected body, flat Z=0 base and nonempty horizontal cross-sections every 0.4 mm. Each exact CAD source was independently compiled and compared within 0.02 mm bounds, 0.5% relative volume and 1% symmetric-difference volume tolerances. All 100 exact STLs sliced in OrcaSlicer 2.4.2 using K1 SE 0.4 mm / Generic PLA / 0.16 mm / 3 walls / 15% infill / normal automatic supports aligned to model layers / base down. Every named layer has nonempty extrusion paths; checked paths stay within the profile bed and height. Per-file hashes, dimensions and scoped source/slicer reports are included.

Software checks only. Physical printing, support removal, fine-detail survival, strength, adhesion, surface quality, fit, resin workflows and other machines/materials remain untested. Review your own slices and make trial prints before scaling. Import in millimeters, base down. Automatic supports were enabled in the recorded slices. No customer G-code or pre-supported files. Each model is a single fixed decorative assembly on a flat seabed base. Vessels, treasure chests, cargo, bell-like forms, lanterns and ship fragments are closed or fixed. Some models have blind decorative recesses. No working lights, bells or mechanisms, usable interiors, water use, guaranteed figure clearance or common figure scale. Actual mesh renders are fitted separately. Digital files only; no physical goods, paint, textures or game rules.
