Small funnel with wide mouth

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
