This is just a small funnel with a wide mouth that I use for adding solid plant food to a one gallon jug and diluting with water.  I was using a paper funnel that had too small an opening for the clumpy solid, and the paper would get wet and clog and tear etc...  Now I know you can buy a plastic funnel anywhere for cheaper than it cost to print.... but what fun would that be?  This funnel is 75mm tall, 75mm OD at the large end, 25mm OD at the small end.  It is 3mm thick leaving the large opening 72mm and the small 22mm.  I used red PLA because that is what was already loaded.  I went with the standard Cura settings for fine prints and used 200 degree (celsius) nozzle temp and 60 degree (celsius) bed temp. I used a skirt for adhesion and support for any overhang though I don't think support was needed. It took longer to print than I expected at over five hours with these settings. It used about 7 meters or 21 grams of filament.  I think you could tweak the settings and get an acceptable print much faster. I designed this object in Tinkercad, sliced it in Cura, and printed it with my Creality CR-10.  It came out great and works well with almost no cleanup required. 3mm seems a good thickness as it is quite strong without using excessive filament.  - Happy Printing, Sonic Ox
