Juwel insert for using a feeding tube

I wanted to use a feeding jar in my aquarium to prevent the food from scattering and to give the slower fish a chance to get to the food. However, I mostly use an automatic feeder and was faced with the problem of getting the food into the jar.

I designed a kind of funnel that can be inserted into the lid of a Juwel aquarium. A tube is inserted into the funnel, which safely transports the sinking food into the feeding tube.

I use this inexpensive feeding tube: https://amzn.eu/d/4urzKFs

I'm really a layman when it comes to designing, but maybe sharing it will help someone.
