EDC Survival Kit

thingiverse

Humans designed this device to carry essential tools in a compact form, including keys, a small USB drive, a whistle, and a fire steel. The whistle is cleverly repurposed from a backpack buckle, proving that even the smallest components can be functional. However, users will need to drill a hole for attaching the keychain and potentially adjust the fit of the USB stick support and whistle to ensure seamless integration.
