Samsung Galaxy SmartTag2 slim mod

Slim Wallet Mod for Samsung Galaxy SmartTag2 (with Coin Tray)

I tend to misplace my wallet from time to time, and while the Samsung Galaxy SmartTag2 is great for tracking, its original form is just too bulky for my taste. It takes up valuable space and makes a slim wallet feel bloated. So I designed this custom mod to make the SmartTag slimmer and more wallet-friendly—perfect for those who prefer a minimalist carry.

This 3D printable design integrates the SmartTag2 into a compact housing that fits neatly into most wallets. It also includes a small coin tray, which adds a bit of extra utility. I connected the SmartTag using simple wire ties on the terminals. It works well enough, but if you have soldering tools, I recommend soldering the connections for better durability and a cleaner finish.

Then I finished it with some tape on top.

To help others replicate this mod, I’ve included a teardown video at the end of the page. It walks through the disassembly process and shows how to adapt the SmartTag for this slim wallet format.
