3d Printed Fish Cooler Bottle
Introduction: 3d Printed Fish Cooler Bottle
My name is <PERSON> and I’m an international student at College of San Mateo.
I designed 3d printed fish cooler bottle.
Step 1: Background
I used to go fishing on my days off. I would often bring a cooler box to put the fish in along with my fishing gear, but I felt it was hard to bring a big cooler box because I can't always catch fish. I also have to bring things like ice pack to keep the fish fresh in the cooler box, as well as stringers to drain the blood from the fish. In addition, surf fishing has recently become popular in Japan, and it is a hassle to wash the sand from the fish you catch with seawater. Therefore, I decided to make a cooler box like bottle that can be easily dissembled to be cleaned and that both bleed and preserve the fish. Shaped into a compact cooler bottle for each fish, it enables anglers minimize the amount that they have to carry when fishing, and bring it home in the best storage condition for the fish.
Step 2: Concept
I thought of something like the image above. To pull the stored fish out of the product easily without reversing it, the top lid and bottom of this product are removable with the screw feature. Excess water from the fish hurts the fish, so to keep it out of the fish, there is a hole at the bottom of the product that allows the dirty excess water from the fish to run outside of the product. As for the exterior, the conventional cooler box has a square shape, but I chose cylindrical shape to add the screw feature to fully connect with body and lids and to prevent water leakage at the joint. Cylindrical shape also produces strong durability since the contact area that attaches the inside and outside wall of the double-layered structure is larger in a spiral than in a straight line. It also evenly distributes external forces such as shaking and wind pressure, while squares are fragile at the corners when collided by accident. Regarding to appearance, cylindrical shape also enables us to see the stored fish from all angles.
Step 3: Design
This time, I designed the following parts: 1: top lid, 2: parts to hold the fish, 3: exterior, 4: bottom. The numbers of the parts are shown in the assembly diagram above. 411
The detailed design is shown in the next section. In this way, a fish is stored in the bottle.
Step 4: Upper Lid
The two parts of the top lid are shown above: 1-1 is the lid on top of another lid 1-2. Holes shown in 1-2 allow cold water to run into the double-layered structure 3 when 1-2 is tightened with the exterior 3 (water does not enter the center where the fish is placed).
Step 5: Cylindrical Pack for Fish
The part used to hold the fish in place is shown above. The fish is gently held in place by the protruding rubber, and the fish is held upright to allow excess water and blood to discharge into the outside.
Step 6: Exterior
The design of exterior is shown above. It is made into double-layered circular shape, with cold water around the inner wall to cool the whole dimensions of the body. A cylindrical pack (2) with a fish fits the inner diameter of this exterior. It is made from transparent material so that the fish can be seen through it.
Step 7: Lower Lid
The lower lid is shown in the figure above, and as shown in 4-1, there is a penetrating hole which the dirty water and blood from the fish can pass through. Four anti-slip rubber feet, as shown in 4-2, are attached to stabilize the product when it is placed.
Step 8: 3D Printing
3D printing performed with the product model in steps above. The machines, software, and materials used were as follows
(1) Printing Machine: Form 3
(2) CAM Software: PreForm
(3) Material
Rigid resin: 1-2, 3, 4-1
Rubber like resin: 1-1, 2, 4-2
The results of the 3D printing are shown in above picture. Due to the size limitation of the 3D printing machine, the size was reduced to 40% of the size of the blueprint.
Step 9: Result
The following figure shows the 3D printed parts assembled and filled with water. I confirmed that the parts were assembled as instructed in the blueprint. The screws were precisely designed with which the lids and body were fully tied together, and there was no water leakage. However, although a transparent material is used for the exterior, it turned out to be cloudy, making it difficult to see the fish inside. 646
