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.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
