BotW Remote Bomb (Mk4)

A glowing Sheikah Remote Bomb from ‘Legend of Zelda: Breath of the Wild’, suitable for both cosplay and decorative purposes.

Development

There was, at one point, a Mk1 of the Remote Bomb. There were also good reasons why no pictures exist of it. Creating a perfectly smooth spherical object, that is 3D printable, is what is technically referred to in the business as a problem. There were also some design issues with making the decorative rings actually fit flush onto a curved surface. It took some trial and error to find a workflow that worked.

So, after that trial and error, I moved on to the Mk2 (shown below). It looked good, it fitted together well enough, and it lit up nice and bright. All things considered, it was a good result (and many happy customers would agree).

Design Improvements

Determined to perfect the design, I developed the Mk3 and Mk4 iterations. These versions featured better detailing for the midline circle art, stronger top and bottom cap pieces, and an internal structure that was exceptionally sturdy. The most significant advancement was eliminating visible seams while ensuring the design remained printable on an FDM printer. This culminated in the current design, which boasts seamless assembly and enhanced durability.

Creation

The first version of this project was... mostly bits and pieces that didn’t actually fit together, or at least didn’t fit together well enough to meet my requirements for a “quality finished product.” However, it did help me to iron out a large number of production and workflow issues I had back in the early days, so as an experience it was more than worthwhile.

The main central body, base, and handle-cap are now FDM printed using plant-based thermoplastics. The designs were optimized for smooth external perimeters and minimal internal supports, reducing material waste.

The circular external decorations are created using UV-reactive resin, ensuring high-quality and smoothness that FDM printing alone couldn’t achieve.

The internal electronics are made using an embedded 18650 lithium-ion rechargeable battery, wired up to a recharge circuit with overcurrent and voltage protection. This is charged via a USB-C port, and powers a ribbon of SMD5050 LEDs winding up through a central diffusor core. All parts soldered with lead-free solder. I'm not a professional electrician, but I haven't had a component fail yet, so I'm pretty pleased with how it all goes together!

The development and production of the Legend of Zelda: Breath of the Wild Remote Bomb was a journey of continuous improvement. From early challenges to refined designs, each step contributed to a high-quality, durable, and visually stunning final product.
