STL file for venturi doesn't have a documented scale... #2

Open davidbuzz opened 4 years ago

davidbuzz commented 4 years ago

With reference to the file venturi_ver02.stl in "Wheezer/3D prints" folder, there's no documented scale for that part. When i tried to open it in a 3d viewer, it showed up as approx 2.85mm diameter, while i'm assuming means it should actually be 28.5mm outside diameter.? I took a clue from the Arduino code that says the larger inside diameter is expected by the code to be 0.875 inches (22.22mm), so an external model diameter of 28mm seems about right, but it's just a guess.

This project was done in 2017, so I'll need to remember back a while. From what I remember, the CAD model we made in autodesk had correct dimensions but it came into the slicer with a scaling problem. We had to multiply it by a factor of 10 to get the correct dimensions on the 3D printer. Apologies for the late response.
