OpenSCAD BCI Hardware

Parametric 3D models for brain-computer interface and neuromodulation hardware.

Assets Index

| Model | File | Purpose | |---|---|---| | Electrode Holder Mod | electrode_holder_mod.scad | Modified EEG electrode holder for dry/wet electrodes | | Paste Adapter | paste_adapter.scad | Conductive paste application adapter for wet EEG | | Headset Hook | headset_hook.scad | Mounting hook for BCI headset suspension | | C3/C4 Pogo Comb | c3c4_pogo_comb.scad | Spring-loaded pogo pin electrode comb for motor cortex (C3/C4 10-20 system) | | fNIRS ECU Housing | ecu_housing_base.stl + ecu_housing_lid.stl | OpenNIRScap electronics enclosure | | fNIRS Sensor Capsule | sensor_capsule.stl | Light source/detector capsule for fNIRS optodes | | Electrode Plate 8-up | electrode_plate_8up.stl | 8-position electrode array plate | | Eurorack Frame | frame-rail.stl, frame-connector.stl, frame-stand.stl | Moduleur eurorack housing for BCI signal chain |

Usage

# Render STL from SCAD
openscad -o output.stl -D 'electrode_diameter=10' electrode_holder_mod.scad

# Batch render all SCAD files
for f in *.scad; do openscad -o "${f%.scad}.stl" "$f"; done

Design Constraints

  • All models parametric (electrode diameter, spacing, head circumference)
  • Print orientation: flat side down, no supports needed for most parts
  • Material: PETG recommended for skin contact (autoclavable)
  • Tolerances: 0.2mm for press-fit, 0.4mm for sliding fit

Integration

  • Pairs with zig-syrup-bci for signal acquisition firmware
  • Pairs with opennirscap-build for fNIRS cap assembly
  • Pairs with cyton-dongle for OpenBCI Cyton/Daisy connection
