	[[File:Tesla SRDU cooling.png\|none\|thumb\|Tesla SRDU cooling]]		[[File:Tesla SRDU cooling.png\|none\|thumb\|Tesla SRDU cooling]]Various step files for printing your own coolant port here:

			https://www.printables.com/model/1693168-tesla-model-s-rear-sdu-coolant-port

			There are three files - a dxf which is the basic outline if you want to cut your own plate and thread it yourself. There is a BSPT version, which has a 3/8in thread for a hosetail, or a complete version with outlet attached. You will need to make your own choice regarding material to use.
