The bending actuators have strain limiting bottoms. These are made from Ecoflex 0030/0050 covered fabric and attached with a fresh batch of Ecoflex 0030/0050 acting as glue.

#### Casting Silicone Coated Fabric

- Place a piece of fabric on a flat non-absorbent surface
- Mix a batch of Ecoflex
- Pour a small amount of uncured Ecoflex onto the fabric surface
- Used a gloved finger to smear the uncured silicone so that it covers the surface with a layer of silicone that is approximately 1 mm thick
- Allow the silicone 4 hours to cure at room temperature

#### Cutting Bottom Part

- Place the cured silicone-coated fabric on a flat surface
- Measure out an appropriate sized piece by placing the actuator top parts on top of it
- Cut the piece with a pair of scissors
