This 3D printed stereotaxic device was designed to be simple, modifiable, and low profile. It includes a gas anesthesia mask which has a vacuum line attached to the mask, as well as a mini down-draft table below the animal to scavenge excess gas.
Disclaimer: your printer might not print air-tight parts, so if you use this with anesthetic gasses make sure to monitor for leaks - if you can smell the anesthetic gas it means there's a leak and you should stop using it! Coating the parts with acrylic or epoxy may reduce leaks.
