Use this part in combination with the Dragon Transport REAR Stud (left side) to replace a broken left hand (top or bottom) Dragon Transport stud.
You'll need to clean the powder out of the holes first. I then spray varnish on the studs as the sintered effect of the 3D print can get grubby quickly. Use the screws from the original studs to slowly cut threads inside, but be careful not to crack to studs by cutting the screw in one turns at a time - each time removing the screw to clean it of debris. Once the screws can go all the way in, use epoxy on the front stud to glue it into the rear stud and use the REAR screw in the front to hold the studs together while they dry.
