Future release — coming 2027. This product is currently undergoing routine testing and quality assurance. It is a preview only and is not yet available to purchase or pre-order. Design, specifications, pricing and release dates may change.

The Medium Outworld is a modular feeding and foraging area for growing or established colonies needing more room for feeding, maintenance and foraging. It offers space to provide food and water, remove waste and observe colony activity while the ants remain housed in a suitable nest or test tube.

Assembly required: Supplied as separate components for assembly before use. Required fixings are included. Check all lids, panels, connectors and unused ports for a secure fit before introducing ants.

More space for growing colonies and modular expansion

The redesigned enclosure uses a grey acrylic floor, clear acrylic wall and top panels, and 3D-printed PLA upper and lower framing. It replaces the earlier PLA-floor assembly approach.

  • Design dimensions: approximately 120 × 100 × 90 mm
  • Modular ports: 2
  • Colours: Black or Dark Green
  • Construction: acrylic floor and panels, PLA framing and assembly fixings

Compared with the Small Outworld, this model offers more practical foraging space for colonies that need it. Connect to compatible Antastic Tom nesting equipment, securing every connection and unused port before introducing ants. No fixed worker number determines when to upgrade: select a size appropriate to the species and day-to-day care requirements.

What is included: the outworld body components, acrylic panels and assembly fittings. Food, feeders, nesting accommodation and ants are not included.

Safety: Check all lids, panels, screws and connectors for gaps after assembly and during use. Use an appropriate escape barrier where needed, avoid exposed water pools, and keep PLA and acrylic away from direct sunlight and uncontrolled heat. See the modular compatibility guide and Product Safety & Suitability information.

What’s included

  • 3D-printed PLA upper and lower frame components
  • Grey acrylic floor panel
  • Clear acrylic wall panels
  • Clear acrylic top and access-lid components
  • Assembly fixings
  • Modular connection fittings appropriate to the supplied design

Ants, nesting accommodation, feeding equipment and decorative substrate are not included. The revised construction uses an acrylic floor rather than the solid PLA floor of the Original Starter Outworld. Exact assembly hardware quantities should follow the components supplied with the current model.

Dimensions and compatibility

Design external dimensions: approximately 120 × 100 × 90 mm.

Materials: grey acrylic floor, clear acrylic enclosure panels and 3D-printed PLA upper/lower framing, with suitable assembly fixings.

2 modular connection points for suitable Antastic Tom equipment. Verify all connecting parts and unused port seals before use; compatibility depends on secure fit, not simply matching the nominal size.

This is the redesigned acrylic-floor construction, not the previous PLA-floor Original Starter Outworld.

Who it’s for

Suitable for growing or established colonies needing more room for feeding, maintenance and foraging.

There is no fixed worker-count threshold for an outworld of this size. Choose according to species, worker activity, available floor space and ease of feeding and cleaning.

An outworld is a foraging and feeding space; it does not replace a suitable nest or test tube.

Setup and use

  1. Identify the grey acrylic floor panel, clear acrylic sides/top and the printed upper and lower frame components before starting assembly.
  2. Position the acrylic pieces in their matching frame locations and secure the supplied fixings gradually. Ensure all panels are seated correctly and do not overtighten screws.
  3. Fit the access lid and verify that it opens, closes and sits flush without distortion.
  4. Connect the outworld to a suitable test tube or nest using the supplied compatible modular fittings. Secure every connection and close unused ports before allowing ants access.
  5. Inspect the entire enclosure for gaps, warping or loose joints. Provide an appropriate species-specific escape barrier where needed; a barrier does not replace a properly assembled enclosure.
  6. Offer food and water in safe, easy-to-clean receptacles. Avoid exposed pools of liquid and prevent substrate or decorations from bridging the walls and lid.

Care and maintenance

Regular checks

  • Remove uneaten food and accessible waste before it spoils.
  • Check the access lid, acrylic floor, wall panels, upper and lower frames, screws and modular connections for looseness, damage, warping or escape gaps.
  • Keep substrate and decorations away from the upper containment edges. Stop using the enclosure if any damage creates a possible escape route.

Cleaning

When unoccupied, clean acrylic and PLA parts with lukewarm water and a soft cloth or brush. Allow everything to dry before reassembly. Avoid boiling water, dishwashers, abrasive pads, alcohol and strong solvents. Keep PLA out of direct sunlight and away from uncontrolled heat.

Frequently asked questions

When should I move to a Medium Outworld?

When the existing foraging area makes feeding, water provision or cleaning difficult, or the colony needs more practical space. A fixed worker threshold is not reliable.

What are the two connection points for?

They allow compatible modular equipment to be connected or future expansion, with any unused connection securely closed.

Is it the earlier PLA-base Medium Outworld?

No. This redesigned model uses acrylic-floor construction with upper and lower PLA framing. Follow the current product dimensions and supplied assembly parts.

Can food be offered inside it?

Yes. It is designed as a feeding and foraging area; use safe feeders and remove perishable leftovers.

Does it replace a nest?

No. It must be paired with appropriately sized nesting accommodation.
