Mini automatic fish feeder

Part of my upcoming project of smart aquarium, which is currently in stage of testing and documenting.
Automatic fish feeder dispenser, I was inspired by this great design, https://www.thingiverse.com/thing:2761061 but after printing I thought it was quite big so I tried to maximally minify the design to be still functional but much smaller.

Servo is rotating in angle of 45 degrees, I did not include any details of driving or programming the servo itself, as I will describe this as part of whole aquarium controlling device.

This is the first version, I have 2 possible upgrades of this in head, and hopefully I will translate these into sketches, do some test 3D print and publish it online. One is some way of controlling the amount of granules it will dispense, by turning some wheel probably, I think it would be compatible with this first version printed. Second would be bigger funnels, eventually I will try to design thread as
