1 inch PVC 3 way elbow joint

Don't forget to test the pipes before joining them with PVC cement! Printed with a 0.35 layer height, and the pipes fit together with just a small gap - I used tape around the pipe for a solid connection. If you're using supports, use minimal ones because overhangs can make the pipe not fit properly. This should work with ABS and other types of materials too.
