Rubber band hook for 6mm foams

thingiverse

Small hook for rubber bands - very useful to secure batteries / lipo sensors. They can handle moderate loads but are NOT to be trusted for critical structures (eg securing wings....do so at your own risk!) Cut a small slot at 45 degree angle in the foam, fill with hot glue or equivalent, then press in diagonally so the foam 'tooth' slides in neatly. Some glue on the foam surface itself may help but most of the strength is in the tooth engaged in the foam. 2 widths provided.
