About this 3D model
My wife wanted a wide funnel. We were unable to find one in the stores, so I whipped this up in OnShape. Choose your material wisely … if you are going to use with food, be sure to choose a food safe filament that you are comfortable with. Print upside down, no supports. I made the wall thickness 1.8 mm … on a 0.4 mm nozzle, on my printer anyway, it kind of printed like a “vase” mode. (0.4 x 4 = 1.8). I added photographs by a ruler so you can judge the size of the funnel before downloading.
