Unicorn wireless EEG system enclosure

The Unicorn EEG system is a wireless, portable 8-channel EEG system by the Austrian company g.tec medical engineering designed to make high-quality EEG technology more accessible. First released in 2019, it was available as the "Unicorn Hybrid Black" set and as the "Unicorn Naked", which is only the PCB plus the wires and hybrid electrodes. Both versions are designed for scalp EEG with fixed leads/wires.

To make it more versatile, on https://robertoostenveld.nl/unicorn-naked-case/ I have described an alternative 3D-printed case and 2x5 standard header to allow connecting other types of electrodes for EEG, EMG and ECG. The thing I am sharing here is the first version of my Unicorn enclosure with the soldered 2x8 shrouded header as documented on my blog in 2022. For the second version that is documented elsewhere I switched to an 2x5 insulation displacement connector (IDC).

The original Unicorn Hybrid Black comes with EEG caps in different sizes that allow the EEG system to be cliped-on at the back of the cap with magnets. The enclosure design includes a part where you can glue in two neodymium magnets, and I also included the design for a compatible magnetic holder that you can mount on your own cap.

I printed it with black PLA on my Prusa MK3S, if I recall correctly with a 0.25 mm nozzle. I would expect it also to print fine with a 0.4 mm nozzle.
