Product Description
This is the Brachycephalic shape variant of the M4 frame. That means it is more appropriate for the rounder head shape commonly found in Asia and Pacific populations.
The M4-Ultra headset is compatible with the OpenBCI M4 Ultracortex system. This new frame design does not require threaded inserts in each node, since the SLS nylon process is precise enough for functional threads. This design is also stronger and lighter than a headset printed using the FDM extrusion process. Octabolt electrode assemblies are not included. Octabolt electrode kits ("Print it yourself" kit. Link does not include the headset frame, which you will need to purchase here), or the OpenBCI Cyton Board, can be purchased from the OpenBCI store.
More information about headset sizing.
M4 Ultra Brachycephalic frame is currently available in Medium size. This size will still fit large and small brachycephalic heads better than any size of the standard shape:
Circumfrence: 52.6cm (Instead of 55.2cm)
Length: 17.6cm (instead of 19.2cm)
Width: 15.8cm (instead of 14.4cm)
9cm high from circumference line (same)
Cephalic index is defined by the ratio of head width to length times 100. The Brachycephalic frame has an index of 89.7, and the standard frame is 75 (mesocephalic). If most frequent users of the headset will have a cephalic index over 75, consider buying this version.
More about 3D printed nylon:
At this thickness, the nylon is not as flexible, but it is very tough and strong. It has a higher detail and is less prone to cracking than extrusion-printed plastics. It has a matte finish and slightly grainy feel. Due to its porosity it may be useful to seal nylon with a laquer spray, or it can be ordered in dyed material. The pure white nylon can be refreshed using 200-grit sandpaper.
