Critique and Support

Hey all,

I'm trying to teach myself more about 3d printing and CAD - I'm trying to design a bowl holder for my cat with a mote to hold water down the bottom to combat ants. I'm wondering why when I go to send it to the printers, the quote is like $2000? I think it's the sizing but it seems to be all in mm? Keen for any ideas or general critiques!

Thanks all.
