about me


Welcome to my online shop! My name is Frederik Schatz what's behind that Fresch hidden, and I would like to tell you my story.


At 36 years old, I am a passionate mechanical engineer and have a great affinity for technology. In addition to my professional activity, I discover two special hobbies in my free time: diving and 3D printing. These two passions fueled my creative mind and inspired me to create a unique project.



During lockdown in 2020, I was faced with the challenge of finding a suitable case for my own dive computer, the Suunto Eon Core. However, to my surprise, there was no suitable solution on the market. As a technology enthusiast with a penchant for creativity, I quickly decided to design my own cases and produce them with my 3D printer.

What started as a personal necessity has developed over time into an exciting project. I have continued to improve my 3D printing skills and have designed a variety of cases for different dive computer models. My focus has always been on offering high-quality products that optimally protect the diving computer and at the same time offer an attractive design.


Today I am pleased to be able to present you a selection of my diving computer cases in my online shop. Each case is carefully designed and manufactured to meet the highest quality standards. You can rest assured that your dive computer is safe and protected in one of my cases.


My goal is to offer divers around the world high-quality products that support their passion. The positive feedback from my customers from different countries encourages me to continually expand my product range and continually develop new designs.


I cordially invite you to explore my online shop and convince yourself of the quality and variety of my diving computer cases. If you have any questions or special requirements, I will be happy to help you. Thank you for your interest and support!

Diving is a fascinating sport that inspires a large number of people around the world. Diving computers are indispensable companions because they provide important information such as diving depth, diving time and decompression limits. When choosing material for dive computer cases, TPU (thermoplastic polyurethane) is an excellent option. TPU offers a number of advantages that make it an ideal material for diving computer cases. In addition, TPU can be easily placed over the dive computer, similar to a smartphone case.

High flexibility and adaptability:

TPU is an extremely flexible and elastic material. This allows the dive computer case to conform to the contours of the dive computer and ensure a secure fit. Similar to a smartphone case, the TPU case can be easily placed over the dive computer, ensuring easy handling.

  • Compostability

    Another advantage of TPU is its good compostability. Unlike traditional plastics, which take many years to decompose, TPU can be broken down in industrial composting plants. It can be reused in a biological cycle and thus contributes to reducing waste and protecting the environment.

  • Chemical resistance:

    TPU is chemically resistant to many substances such as salt water, sunscreen, oils and other chemicals that may occur during diving. This ensures that the diving computer case retains its shape and strength even under adverse conditions and is not damaged by corrosive substances.

  • Shock and impact resistance:

    When diving, it is inevitable that the dive computer will be exposed to various shocks and impacts. TPU has high shock and impact resistance, so it effectively protects the diving computer from damage caused by shocks, falls or collisions. This is particularly important to preserve the sensitive electronic components of the dive computer.


Choosing the right material for dive computer cases is of great importance to ensure the protection and functionality of the dive computer. TPU meets these requirements in an impressive way. Its high flexibility and adaptability allow it to be easily slipped on like a smartphone case, while its shock resistance and chemical resistance reliably protect the diving computer. In addition, TPU is compostable, which increases its usability
