About this End Cap

An end cap seals a duct end you are not using. It slides into the open port with a friction fit, so the air stays in the line and all the pull goes to the tool you are running.

Set one size, the inside of the duct it plugs. It prints closed end down with no supports, and the socket grips the wall so it holds with no clamps in most setups.
