The file 'PVC Vent Flange – 3.5 3D Printer Model' is (STL) file type, size is 1015.4KB.
My propane stove uses 3.5" PVC piping to vent to the outdoors. These pipes needed a little sprucing up.
After sealing around the pipes to create an air/water tight barrier, a set of flanges can be screwed into place using standard wood screws.
Each set of parts will give you a flange of the following rough dimensions:
Ø3.585" ID, Ø5.250" OD, 1.00" protrusion
