The file 'Merge Collector Jig 3D Printer Model' is (stl) file type, size is 1.1MB.
A cutting jig for making a 15deg 4-1 merge collector of a 42.4mm pipe, with a built in 90deg marker and a hole for a M6 screw and 10mm m6 nut.
Just put the pip in the jig, tightening the locking screw, mark on one side of the 90deg flange and cut, then rotate the pipe so that the marking lines up on the other side of the 90deg flange and cut again. Repeat three more times and you have the fore pipes for a collector
