Octocore Outworld (Series X)
The Octocore Outworld is our large-format foraging arena, designed for expanding colonies with hundreds to thousands of workers. It provides generous space for natural exploration and foraging behaviour—making it especially exciting for ant keepers to observe in action.
Perfect for those scaling up their setup, the Octocore can also be purchased as part of a bundle with the matching Large Nest, offering a slightly reduced price for a complete modular habitat system.
 
Key Features
8 modular connection ports for maximum expansion flexibility 
Integrated sliding door system on every port for safe colony control and easy management 
Double-lipped lid system to reduce escape risk 
First lip designed for applying ant barriers 
Oversized lid design for easy access and thorough cleaning 
Large integrated handle for safe lifting and repositioning 
Robust, easy-assembly construction built for long-term durability 
Assembly Guide
We recommend following our Vertex assembly video, we have added it in our images on this product page, as the construction method is very similar.
To assemble:
Start with the base and carefully remove all protective film from acrylic parts 
Identify the two longer and two shorter side panels Marked 2 and 1 respectively 
Attach the two shorter panels to opposite sides of the base 
Repeat with the two longer panels 
Ensure all panels sit flush with no gaps before tightening 
Secure screws firmly, but do not overtighten 
Once the frame is complete:
Place the top frame onto the structure and screw it into place 
Fit the first-lip lid on top of the frame and secure it with screws 
Remove protective film from the ventilated acrylic lid panel 
Attach the second lip frame to the lid and install the handle (facing outward) 
Finish by placing the second lip lid on top 
Refer to product images for correct final orientation and assembly confirmation.
Important Note
One hex key is supplied per order, not per individual unit.
Example: ordering two nests (or a nest and outworld) includes one hex key total.

Why Series X Stands Out
Door Slide Technology™ — Total Control
Integrated sliding doors let you instantly isolate or open sections safely, making expansion and maintenance simple while significantly reducing escape risk.
Bigger Chambers, Better Value
Our chambers are 10–20% larger than many comparable systems, giving colonies more usable space and improved long-term value.
PETG Construction — Built for Strength and Longevity
Unlike standard PLA systems, PETG offers:
Improved warp resistance 
Higher temperature tolerance 
Safe cleaning up to 60°C 
Long-term durability for repeated use 
Premium Hardware
We use A2 stainless steel screws as standard—offering superior strength and rust resistance compared to zinc alternatives.
Smarter Outworld Design
Vertical, space-efficient layout 
Minimal assembly required 
Secure double-lipped escape-resistant lid system 
True Modularity
With 8 connection points, you can expand freely using tubing, nests, outworlds, or test tube adapters—building your setup your way.
Built to Last. Built for Keepers. Built for the Future.
Series X is engineered for decades of use, not seasons.
Less waste. Greater durability. Better long-term value.
If you’re looking for reliability, innovation, and professional-grade quality without unnecessary markup, Series X is the future of ant keeping.
