CAD design files for a programmable thermoelectric thermotaxis system

This repository contains editable CAD design files and associated 3D virtual models developed for a programmable thermoelectric thermotaxis platform designed for thermal-related behavioural assays in small aquatic organisms. The deposited files include experimental chamber designs for generating stable temperature gradients or binary thermal zones, thermoelectric system assembly components, mounting structures, and 3D virtual models. These models can be viewed on Apple mobile devices, including iPhone, iPad, and Apple Vision Pro. All dimensions are specified in millimetres, and the primary construction material is polymethyl methacrylate (PMMA). These design files correspond directly to the experimental apparatus described in the associated manuscript and are provided to support the application of this platform for assessing thermally guided behaviours in small aquatic animals.
