Underground Reptile Hide

An engineered, flush-mount underground hide designed to integrate seamlessly into bioactive terrariums. Featuring a removable lid for zero-disturbance access and an open-bottom architecture to maximize substrate exposure, this hide excels at maintaining isolated microclimates (ideal for humid hides using a damp 70% topsoil / 30% play sand mix).

CHANGELOG: V1.2 (True-Scale Update)

• True-Scale Profiles Added: Uploaded independently engineered Small, Medium, and Large profiles. Unlike standard slicer scaling which dangerously thins out walls, every astroviv size maintains a strict structural wall thickness.

• Optimized Internal Geometry: Refined internal radiuses for improved continuous curvature.

• Technical Documentation: Added official engineering dimension blueprints to the gallery.

Engineered for Pet Safety

Reptile health is our top design priority. Standard amateur 3D models are often built with sharp digital corners and un-chamfered 90-degree angles that can cause micro-abrasions to delicate reptile scales and amphibian underbellies.

• Continuous Curvature: The astroviv hide is engineered with perfectly smooth, continuous-curvature internal radiuses to eliminate sharp edges entirely.

• Structural Integrity: The strict 1.2mm wall thickness ensures the hide will not crack, splinter, or collapse under the weight of substrate or hardscape elements.

Core Features

• Modular Entrances: Includes interchangeable "Left" and "Right" mirrored lids, allowing you to optimize the entrance placement for your specific hardscape layout.

• Dual Base Architecture: Choose between the Standard Base (fully enclosed walls with calculated ventilation/peep holes) or the Tunneling Base (features integrated wall openings, allowing burrowing species to excavate their own tunnel networks directly from the hide).

Material & Safety Disclosures (Please Read)

• Thermal Limits (PLA vs. PETG): Do not place PLA prints directly under ceramic heat emitters (CHEs) or high-wattage basking bulbs. PLA has a low glass-transition temperature and will warp or melt. If your hide will be exposed to direct, high heat, print the provided profiles using PETG or ABS/ASA.

• Bacterial Sealing: FDM prints are naturally porous. To prevent bacterial buildup in the layer lines, seal the interior of the hide with a reptile-safe sealant before introducing it to a high-humidity environment. Polyurethane spray sealants provide an excellent clear-coat.

• Curing Time / Off-gassing: If using a spray sealant, allow the print to cure in a well-ventilated space for at least 48–72 hours. Do not place the hide in an enclosure until all chemical fumes have completely dissipated.

Fabrication Specifications

• Supports: Slicer supports are required strictly for the underside of the lid overhang. Slim tree supports provide excellent results and easy removal.

• Fuzzy Skin: The included .3mf files contain profiles for both standard and "Fuzzy Skin" exterior walls. Fuzzy skin provides a premium, natural rock texture and aids reptiles during the shedding process.

Edit 2025/01/28:

STL files have been added in place of STEP files so they can be viewed in the native 3D viewer in Printables.

Edit 2025/06/14:

STEP files have been added back in place of STL to rectify failed prints when using STL files - see @Smithy18772_2201999 's comments. Many thanks for helping troubleshoot the failed prints!

Edit 2026/03/05:

STL files have been regenerated and reuploaded.
