The file '3 Inch Y Exhaust Pipe Cutting Gauge Pattern Jig 3D Printer Model' is (stl) file type, size is 66.8KB.
I felt it was easier to design and print this instead of just hacking on my exhaust pipe.
It slides over a 3" exhaust pipe and allows you to properly mark the cut lines you need to make to piece together a 3" Y pipe.
The pipes are coming off the main pipe at 45 degrees, therefore the output pipes are 90 degrees apart.
Picture shows my mostly finished Y pipe.
It also can be used to mark straight cuts.
