This is a remix of Pet Litter Scooper - No Supports by Triple G Workshop. 

The remix adds an additional grid line at the bottom to make the holes a bit tighter (so small dirty cat litter pieces won't fall through). The line thickness is adjusted accordingly so we don't lose too much of the opening. 

Supports are still not needed as the basic shapes remained the same.

Additionally the handle was elongated by around a centimeter. By doing so there is more space to comfortably get your fingers in between the handle and the shovel. 

I've remade the entire model in onshape and then altered it, reason being is that I think the basic design of the original model is great, the changes were simply to address minor gripes my girlfriend had with it's use.
