Prosthetic Handheld Vacuum Attachment

This prosthetic is an attachment to a pre-existing prosthetic arm.

The hand attachment is made of general PLA. The flat circular base is bolted to the prosthetic arm wrist. This part has a component with a clip, composed of two arrows with pins. This clip corresponds to a clip eater component on the vacuum attachment. Push the pins together, slide it into the clip eater, and once it hit the end the two interlock. Push the pins back together and slide it out to seperate.

The vacuum attachment should be printed with TPU material for flexibility. The piece has 0.2" diameter holes on two parallel sheets connected to the open sections of the cylinder. A bolt and nut can be used through these holes to tighten the cylinder around the handle of a handheld vacuum. The bolt and cap models I created are available, but they deformed when printing so I recommend not using them and instead either modeling different bolts and caps or purchasing metal bolts and nuts.
