Made an air mattress plug this week.

Over a year ago we lost the plug to our air mattress. A couple weeks ago my wife says to me “why don’t you print a new one?” And so I have.

Took a few tries to get the thread right for the one way valve (24mm outer diameter, 30° pitch on the thread at 13 turns per inch). I then copied that thread model, reduced the diameter it for the inside thread and then reduced it some more for the plug.

Added a rubber flapper and some O-rings.

Inflated the mattress and now we wait and see if it holds air…

Well it’s still holding air! I was concerned the layers would not be air tight. Looks like I’ve got a winner.

One slicer I looked at the other day had an option for water tight. Not sure what one it was but could be of value if you have issues

dip it in tool dip to give it a rubberized outer shell.
