Drain Pipe Standoff for Water Softener

This is a standoff for a .5" OD drain tube from a water softener or other appliance that goes to a 1.5" ID sewer pipe. It provides a 2" air gap to comply with codes, depending on where you live. Print with the half inch hole side down and preferably with ABS as it will likely hold up to moisture and salt water better than PLA.
