This is an enclosure for the OpenBCI Cyton and Ganglion biosensing boards. It exposes eight touch-proof connectors (8x1 for the Cyton or 4x2 for the Ganglion) plus a connector for the common reference and for the ground. It comes with an external on/off switch and a micro-USB port for charging the LiPo battery. Although I did not try it, the enclosure should be high enough to mount an additional WiFi field on the board.
The complete design includes the following additional components:
The model is designed in Fusion 360 and is fully parametric; so it can be changed if needed.
Disclaimer: This design and the OpenBCI board are not medical devices, nor are they intended for medical diagnosis.

I used double-sided adhesive tape to attach the battery and the LiPo charger module, and regular glue to secure the on/off switch and the LED. Subsequently, I used hot-glue to secure all components firmly in place, especially the ones on which pressure will be applied during normal use (the switch and the charger).
I used hot-glue to attach two 1 mm diameter light fibers between the LEDs on the LiPo charger module board and the small holes above the USB connector. However, the light scatters too much and the two LEDs can be seen but not distinguished from each other on the outside. This could use some improvements.
