Miniature Water Bottle

WE'RE DEAD WITHOUT WATER! The average human body is made up of 60% water, meaning we need to stay hydrated. Therefore, humans need a water bottle for on-the-go hydration. A perk to water bottles is that they come in different styles, colors, and sizes. Luckily, I made a miniature water bottle for quick sips of water whenever and wherever. The compact size allows for quick refreshment without the hassle of carrying a regular water bottle.

My design process for the Miniature Water Bottle initiated with finding a way for a quick refreshment with a funny twist by being miniature. The original idea was to take a Yeti Rambler and size it down to make a 1/3-sized replica. I took the measurements of each piece and divided it by 3 to get the sizes. During the beginning process of designing, I noticed a constraint having to do with the correct calculations. The problem was having to use precise measurement and placement with small numbers. Although I did face this problem multiple times, I overcame it by using exact decimals and different Onshape features that are more efficient.

The Miniature Water Bottle was designed in Onshape to be able to 3D print it. If there is no 3D printer available for use, you can build the project with recyclable pieces found near you. For example, using cardboard, melted hot glue, or even paper. Though for this design, I took the 3D printed route. These are the following tools used to build and correct my project:

• 3D printer
• Hot glue gun
• Scissors or Box cutter
• Small Pliers

To begin with, extrude a cylinder with a 2.333 inches height. Add a second cylinder sketch on the bottom face of the first extrusion, extrude a height of 0.333 inches, and use the Fillet feature to round the edges to 0.1 inch. Next, create a third sketch on the top of the whole cylinder of a 1.5-diameter circle and remove the extrusion down 2.3 inches. Then create a Helix on the inside of the cylinder to screw on the lid to the cup.

Create a new Part Studio

Afterward, extrude a cylinder of 0.3 inches and create a Helix on the outside of it. On a second sketch, on the front face, extrude a cylinder of 1/12 inch. Use the Fillet feature to round the edges of this piece. After the extrusion, add a third sketch on the bottom face of the whole part that will remove a 0.8-inch hole, only leaving 0.3 inches left from the top. Next, create a fourth sketch on the face of the whole part's top. There you will add a cylinder extrusion of 0.333 inches wide and 0.208 inches high. Then create a fifth sketch on the face of the previous extrusion. This extrusion will turn into an open hole (0.3 diameters) that will then contain a Helix thread on the outside of it.

Create a new Part Studio

Finally, extrude a circle to the size of 0.35 inches, and then on the part's face use the Chamfer feature with a distance of 0.09 inches. Next, create a second sketch on the top face of the extrusion/chamfer part. On this sketch, trace the middle of the lid and use the Mirror feature to get exact placements across the Front plane. Extrude the second sketch by 0.1 inches. After the extrusion, use the Face Blend feature to smooth out the edges of the lid handle. Then create a third sketch on the face of the side of the lid handle extrusion to create the opening for the handle. Lastly, on the bottom face of the lid, use the Hold feature to remove a 0.333in. wide x 0.15in. deep.

After building all the separate parts, use the Assembly tab in Onshape to combine all the Part Studios. The final design should replicate a Yeti Rambler, except a mini version.

Go ahead and 3D print out the three pieces individually. Gently remove the finished product from the 3D workplace using a scaper to prevent any breakage to the printed pieces. Then you will be able to assemble all pieces.

Along the way of the design process, mishaps are inevitable and can set back the entire project. After printing the Miniature Water Bottle, I noticed that the Lid hole was slightly wider than the hole in the Handle. To fix this, I used small pliers to stretch the hole inside the Handle piece and widen it to fit the Lid's opening. I was able to adjust it to the correct size. I linked a small video to demonstrate the steps I took in fixing the hole.

Another unexpected problem that occurred was that the water bottle's Handle piece broke due to being fragile. To fix the delicate piece, I applied hot glue to the broken pieces and glued them back together. I did not have a more durable glue matter available, so I improvised the best way with the hot glue.

Though these mistakes were avoidable, I was able to learn from them and change the Onshape design for next time. I knew I was almost at the finish line with the pieces, so I didn't give up on it and improvised my way out. So learn from me and KEEP GOING!

In the end, the Miniature Water Bottle was a great project to have in the inventory. The entire engineering design process was a guideline for the development of the water bottle. A plus side to building this water bottle was being able to be creative with the colors and styles. From building a product for quick refreshment to fixing easy mistakes, it all came together to evolve the miniature version of a water bottle.

Thank you for watching this evolution !!
