As you can see, this design includes a reward cup, and I like that, but the design is not finished. I only printed the key parts to check the tolerances and to see how the beak looks in real life.
You could take this on, print my design, and put together the kit it requires, assuming you have that kit.
On my side, I will reward you with filament. Trust me, this will be a great bonus 🍰😉.
I am not connected to the contest organizers, but I do not like unfinished projects.

Minor but cute external modification. Parts that have been changed or added:

I don't have the Otto Starter Creator Kit. I only printed the beak and the part for the ultrasonic sensor to check the clearances.
The wings here are attached to the front servos. Of course, they are not meant to rotate fully, only within a range of about 100 degrees.
I have added STEP files for your convenience; they might be useful to you.
