This project introduces a multi-function scale (ruler) designed to let anyone draw complex curves—like the golden spiral and parabolas—easily and accurately. It targets designers, DIY enthusiasts, and anyone who wants to render beautiful proportions and shapes by hand.

Made of stainless steel, the tool is lightweight yet durable, and sized to fit in the palm of your hand for everyday portability. It's being funded through CAMPFIRE, one of Japan's largest crowdfunding platforms, as a reward-based campaign where backers receive the finished product in return for their support.

Specific figures such as the funding goal, number of backers, or achievement rate are not available from the project page at the time of writing. This article therefore focuses on the product concept and its key selling points, which offer a useful case study for anyone interested in the design tool or DIY markets.

Highlights

  • Targets a niche but compelling demand by centering the product around the "golden ratio," a technical yet visually appealing concept
  • Clearly defines its audience as designers and DIY enthusiasts
  • Concisely highlights practical strengths like portability and durability

Why this campaign attracts support

Editorial analysis based on publicly available information. It is not a confirmed account of why backers chose to give.

This project's appeal starts with its use of the "golden ratio"—a keyword that evokes beauty and expertise, sparking curiosity among people interested in design and craftsmanship. The concrete functional value of easily drawing complex curves gives the product an edge beyond that of an ordinary stationery item.

By clearly defining its target audience as designers and DIY enthusiasts, the project makes it immediately obvious who the product is for, allowing it to resonate strongly with the right people. Specific details—stainless steel construction, light weight, durability, and a palm-sized form factor—also build trust in the product as a practical tool.

In reward-based crowdfunding, success often hinges on offering backers something they genuinely want, such as the product itself. This project succeeds in combining functionality and design appeal for a niche audience seeking a specialized, high-quality tool. That said, since no concrete figures on funding goals or results were available at the time of writing, this article refrains from commenting on the actual fundraising outcome.

A note from the editors

The unique angle of making the golden ratio easy to draw is what stands out most about this project. By clearly narrowing its focus to designers and DIY enthusiasts, it captures a niche yet specialized demand—an interesting reference case for product-development crowdfunding.

That said, since the project page doesn't reveal specific numbers like the funding goal or current support status, this article has focused on analyzing the concept and its appeal rather than performance metrics. If concrete results become available later, we hope to cover the campaign's strategic aspects too, such as pricing and reward design as a reward-based crowdfunding project.

We hope readers find value in this case as an example of how to articulate niche functionality and identify exactly who to reach with it.
