Summary

This is a super-tiny soft robotic actuator. When inflated fully, it will bend about 90°. To make one, print the mold and cast it (more info in the Print Settings and Post-Printing tabs). This isn't really a full project (yet), I was just asked to release the files for this actuator.

Post-Printing

Cast the Mold

Once the mold is printed, mix up a bit of Ecoflex 00-30 and pour it into the opening of the mold. Let it cure for about 4 hours.

Demold and Connect

Once the cast has cured, use your fingertips to pull the cast out of the mold. Insert a short bit of 1/16" tubing into the opening of the actuator and secure it with a zip-tie. Connect it to some low-power source of air, like a squeeze bulb.
