Dogs often rush their food causing potential indigestion and other health issues. The slow feeder bowl design prevents the dog from taking large mouthfuls by separating the food into smaller segments.
Prints without support. 15% fill works well. I suggest using PLA given its food-safe properties. I also suggest printing at least 1mm shell thickness and 5 solid layers top and bottom for better water proofing.
