Modeled after a similar tool a friend had. I modified it with the ability to carry a hex bit for added use. Keep this on your key chain, in your car, tools for your bike and etc. You may notice the reinforced edges of key features, it is intended to out last the previous EDC Tool you had. Printed in Black PLA for the moment, would FDM print in ABS, Nylon or a blend of Polycarbonate or Carbon Fiber for strength and reliability. SLA print in a Rigid or Tough Resin, which will increase time and cost of print, but it would be a solid part.
