Since there has been a big push for Fusion 360, I thought i'd share my latest design utilizing it. It's a magnetically mounted jamming gripper derived from Cornell's positive displacement jamming gripper paper for print auto ejection use for the multi-tool changer delta printer

The Jamming gripper utilizes granular material, coffee beans in this case for its low density and cost. A soft membrane such as a rubber balloon is placed onto an object and a vacuum is created to constrict the coffee beans to grip the material of various shapes making it useful for 3D prints which vary greatly.
Three total pieces colored different for clarity:
Black Piece: Nd magnets in placed within each cylinder to mount underneath the delta printer's effector
Gray Piece: mounts to the top piece to contain the magnets as well as the inlet ports for the positive displacement and vacuum pump lines
White Piece: Seal for the rubber membrane gripper and mesh filter to filter the coffee beans from going into the inlet ports.
The next step is write a plugin to read the last few lines of the g-code prior to the end g-code, to use as the target point for the for jamming gripper to pick up the finished piece to a discrete location.
To be continued...
