Compartment bowl

So I really want this thing called "maju bowl" to track my calorie deficit but as an unemployed young woman I absolutely don’t have the budget for a 60€ bowl. I was looking for something similar that I can 3d print but can’t find anything. Maybe I just suck at searching because I can’t find the right words in English or idk. I would even pay someone to do it for me… I think it’s not complicated to do but I don’t know how to do it or else I would. Can anyone help ?
