3D Printing Guide: Safe & Enriching Rodent Habitats

3D printing offers incredible opportunities to create customized, safe, and enriching habitats tailored specifically for small rodents and furry pets, including Syrian hamsters, dwarf hamsters, gerbils, mice, degus, chinchillas, and rats. Many commercial enclosures lack customization and safety features, making 3D printing a powerful tool for improving pet well-being.

At Habitat Homies, we've spent years refining our approach through rigorous testing and research. We’re excited to share these insights so you can confidently design durable, pet-safe habitats that promote health and happiness!

Recommended Material Selection

  • PETG – Durable, chew-resistant, and dishwasher-safe (up to 140°F / 60°C).
  • ASA & Nylon – Highly durable, chew-resistant, and withstand higher dishwasher temperatures.
  • Avoid PLA – Brittle, prone to breaking, and potentially hazardous if chewed. While often mistaken as pet-safe due to its bio-based origin, PLA can splinter and pose ingestion risks.

Design Principles for Safety

  • Minimize Chewing Risks – Rodents instinctively gnaw, so eliminate small or thin protrusions to prevent accidental ingestion. Prioritize rounded corners and smooth surfaces.
  • Thin, Solid Walls – Use a 2-4mm thickness with 100% infill to prevent hidden cavities where bacteria or mold can grow.
  • Improve Durability – Minimize part cooling (below 20% fan speed) and slow down print speeds to enhance layer adhesion and strength.
  • Reduce Seams – Use scarf seams to create stronger connections, minimize gaps, and reduce bacterial growth. (Scarf seams create a sloped connection rather than a straight cut)

Designing for Easy Cleaning 

  • Easy Disassembly – Modular designs allow for thorough cleaning and sanitation.
  • Smooth Surfaces & Rounded Edges – Smooth surfaces prevent bacteria buildup, while rounded edges improve accessibility for scrubbing.
  • Open Bottoms – Ensure easy access for hand cleaning and water drainage. Avoid hard-to-reach structures like deep tunnels or enclosed spaces that trap waste.
  • Dishwasher Compatibility – Select materials that can withstand dishwasher cleaning (up to 140°F / 60°C) to simplify maintenance.

Designing for Natural Behaviors & Enrichment

  • Textures for Sensory Exploration – Mimic natural surfaces like wood or rock to enhance tactile engagement. Ridged and organic structures provide traction and grip for climbing.
  • Modular & Rearrangeable Components – Allow for habitat modifications to maintain curiosity, prevent boredom, and encourage problem-solving.
  • Vertical Exploration – Multi-level designs and platforms promote natural climbing behaviors. Ensure structures are stable to prevent falls.
  • Hideaways – Covered tops create a sense of security, mimicking natural shelters and protecting against perceived predators.
  • Burrowing – Open bottoms enable pets to shape their dens, including creating escape routes and tunnels.
