If you make this model and like it, please post your make and rate the model, that would make my day!
I made a very small change to an excellent model created by @ericsnis and removed most of the front wall so there's just a small lip there now – this is accurate to the commercial version I wanted to replicate. I also made a simple spatula for it based on spatulas that commonly come with these sorts of trays.
I'm not very experienced with 3D modelling so the spatula is very basic, I'm sure someone could improve it. It does the job though.
