3 Inch Vacuum Hose Plug

This is a 3 inch hose plug used for plugging up the end of an exhaust hose that is not currently attached to a device.I use a worm gear hose clamp, similar to one of these to secure the hose to the plug. A 4 inch version can be found here:https://makerworld.com/en/models/2174838-4-inch-vacuum-hose-plug#profileId-2359324
