Stealthsonic Through wall adapter

Stealthsonic Through wall adapter for use with the Stealthsonic to 2" PVC Adapter (https://makerworld.com/en/models/2255513-stealthsonic-to-2-pvc-adapter#profileId-2456864). Allows for storing the Stealthsonic inside of a cabinet. Through port can be closed for full suction, open for a 50% decrease in suction at the carvera air (but allowing full suction at the vacuum for cooling), or using the smaller port hole to increase suction at the carvera air vacuum hose.
