The file 'Exhaust Assist For Tac Welding 3D Printer Model' is (stl) file type, size is 39.0KB.
I Have seen these in metal online and really needed one for doing my exhaust on a bench, its a really pain the butt holding them while tacing in place. I tested this on 3" pipe which works great, I printed in PLA and it doesnt even get hot really. You can resize in your slicer for different pipe sizes. I print 100% infill to handle the heat a little better and use supports.
