AutoFeeder food funnel for Eheim AquaPro 126 cover

I made this to fit in the hole of the top cover of my Eheim AquaPro 126 aquarium.

The cover has a spot to put the Eheim AutoFeeder but it seems that one must buy also the Eheim feeding station to avoid the food ending up all aound the hole.
Tired of cleaning i made this so that when the autofeeder does its job, nothing is spilled and there will be no food ending up on the plastic around the hole.

This is just my first iteration, if you use food in big flakes then it might be a bit too short but no worries, simply align the Autofeeder to the side closest to you and the problem is solved.

I also evaluated to stretch the bottom and let it reach the water just like the feeding station but I don't know enough about PLA staying in the aquarium water.
