This isn’t your average bottle opener – it's a whimsical, quirky, and endlessly entertaining kitchen gadget that brings a smile to everyone’s face. Shaped like a hilarious blend of animals, this little critter isn’t just here to help you open bottles – it's here to make the whole experience unforgettable. Made from durable, premium-grade steel and crafted with precision using a high-tech water jet cutter, this bottle opener offers you a combination of practicality, goofiness, and quality.

The bottle opener is cut using an advanced water jet cutter, a method that allows us to produce intricate details in the shape of the raccoon-bear character while preserving the integrity and strength of the steel. Water jet cutting is a process that uses high-pressure water (often combined with an abrasive) to slice through metal with extreme accuracy and without generating heat, which can weaken certain materials.

This process not only preserves the strength of the opener, but it also allows us to add fun, intricate details to make this character come to life! The grooves around the eyes, the ridges of its tiny teeth, and the shape of the paws are all thanks to the precision of water jet cutting. You’re getting a bottle opener that’s built to last, withstands repeated use, and keeps that adorable design intact year after year.

Water jet cutting is an advanced and precise method that uses a high-pressure jet of water, sometimes mixed with abrasive materials, to slice through hard substances like metals, ceramics, glass, and even composites. Using this technology to make a bottle opener has become popular due to its high precision, versatility, and ability to create intricate, detailed designs without altering or damaging the material. With a water jet cutter, such as the ProtoMax, you can create a durable, unique bottle opener with exceptional accuracy and minimal material waste.

The process begins with the design stage. Using CAD (Computer-Aided Design) software, such as OnShape, designers create the exact shape and detail of the bottle opener, considering elements like ergonomic grip, bottle cap leverage, and, in many cases, aesthetic or fun designs that add character to the tool. The CAD design is then translated into cutting instructions compatible with the water jet software, such as Omax, which communicates directly with the water jet machine.

When the water jet cutter receives the instructions, it uses pressurized water mixed with abrasive garnet particles to begin cutting the metal sheet. Typically, a bottle opener would use stainless steel or aluminum sheets of approximately 0.09 inches in thickness, chosen for durability and strength. The abrasive particles enhance the water’s cutting power, enabling the jet to slice through thick, tough metals with ease and precision. This “cold cutting” method avoids the heat generation associated with traditional metal-cutting techniques, preventing warping, melting, or altering the structural integrity of the metal.

Water jet cutting is particularly suited to crafting bottle openers because it allows for intricate and customized designs. For instance, the jet can create not only the primary opening slot for leverage but also decorative grooves, curves, or even unique shapes like animal figures, making the opener both functional and visually interesting. The precision of water jet cutting ensures that all edges are clean and smooth, and the finished product requires minimal post-processing, such as sanding or filing.

Overall, water jet cutting offers a powerful, flexible, and sustainable method for producing custom bottle openers. The technology supports a high level of creativity and quality while keeping production efficient and reducing material waste, making it a top choice for crafting durable, well-designed openers.

Supplies

1) A 12x12 in (or larger) Sheet of Aluminum .09 in thick

2)A computer with OnShape (or other CAD) and Omax (or other) software capabilities

3) a ProtoMax (or other) water jet cutter


Design the Bottle Opener in CAD

For my purposes, I used OnShape to design my bottle opener.


Things to make sure of:

-The mouth dimensions are capable of opening a bottle

-The arm's and leg's dimensions are capable of opening cans if you want them to

Export DXF

Select the front face of your object and export a DXF file. Download it to your computer and save it somewhere you can access it.

Preparing for WaterJet Cutting

Open your DXF file in Omax or an equivalent software.


Things to make sure of:

-Start and end of path are not on the actual object

-There are no excess lines or points

Once the sheet of metal is in place and clamped down, and your design is set on top of the sheet, and you have the lid down you may start the waterjet cutter.

Once the process is complete lift the lid, unclamp the sheet, drain the tray, pull all metal out and isolate your object.

Sanding

Next, you should sand the edges of your object so it is smooth to touch and does not cut anyone.

Additionally, you may sand the mouth as shown so the edge of the mouth has an angle which makes opening bottles easier!

Enjoy

Once the product is properly sanded, as shown, you are finished !


The process of waterjet cutting is all about the details. I had to sure my dimensions were correct especially around the mouth (bottle opener) and limbs (can openers). Additionally, the extra lines and points in my DWF file had to be deleted. It may be easier using Adobe Illustrator or an equivalent software to perform such a process. Finally, make sure to be creative and have fun!
