Here are our custom chamber designs for simultaneous behavior and physiology experiments. All renders of chambers were done using Blender. Corresponding photographs show the completed chambers with other devices (operant panels, position trackers, amplifiers, cameras, cables/commutators). To download, right click one of the file links under the pictures and select “save link as…”

In general, we have not fabricated these chambers ourselves, but work with a local plastics company (Dan Kar Plastics) who custom builds based on our specifications. After we are satisfied with a design in Blender, each acrylic piece is exported as a .dxf file which can be translated into machine code for a CNC router. If no changes are required, the .zip of .dxf files we have provided should be sufficient for a custom manufacturer to fabricate the same chambers. If modifications are desired, we have provided the Blender file from which the .dxf files were exported so one can modify and re-export to their specifications.
