Canine Feeder 3D Model Design

I am a professional dog trainer looking to create a product that helps handlers deliver food to their dogs easier. I’m looking to have the following product description 3D printed so I’m needing a 3D model of the device created along with the associated files in order to have the product 3D printed. Description: This product is going to be a handheld product that is 6 inches long, 6 inches in diameter and 2 inches wide. On one end of the product that will be a cap that can be screwed on and off. The main body of the product will be empty and hold all of the dog treats. At the opposite end of the unit there will be a softer plastic piece that will have a slot in it that allows the user to squeeze with their pinky and thumb allowing food to drop out. Think of this piece like a rubber change purse. A change purse is a oval rubber like container that holds coins and that has a slot in one side, when you squeeze the container at each end the slot opens up however when it’s not being squeezed it remains closed. The unit does not need to be completely round, in fact if it’s shaped much like a gun grip that would be even more economical, the device also needs to have finger grips to make it easier for the user to hold the item when their hand gets moist. Included is a design photo that I threw together in order to give a better visual. The design does not need to look like the photo I’m only using it as a point of reference. I am also including a quick video link to how a person holds food in their hand during training to give a better visual reference. I’m also including a video of a change purse to get the idea of the nipple design at the end.
