Use this model of a Berlin Heart to teach kids about their medical procedures and normalize the medical implants by giving dolls or teddybears a Berlin Heart Pump
Print each part in its corresponding color and assemble with hot-glue. All interface surfaces have 1/2mm tolerance so give the pegs a small dollop of hot glue and it will spread to fill the interface volume.
The Tube fittings should snug fit any ½"OD 3/8"ID vinyl tube like you can get at HomeDepot; use either superglue or zip-ties to secure permanently.
If you want to put it on a doll, print the doll adapter and make an “X" incision just large enough for the adapter to fit though. Put some hot glue around the inside of the adapter and push the fabric flaps into that hole. Then add more hot-glue over the fabric in the inside of the adapter and push the tube in.
Let us know if this worked for you or if you have any other ideas.
