Phễu Cơ Bản (Basic Funnel)

The model is solid, it's designed to be printed in spiral aka vase mode. I recommend to define the line width to 0.8-1 mm and the layer height to 0.3 mm. It should be done in less than 15 minutes with an average print speed.

I originally made this to fit into my 2008 Mazda 6 engine pouring oil hole but can suit to other situations.
