Foredom drill chuck key strap

I needed a smaller drill chuck key strap and designed this one. This strap is sized for a Foredom grinder with a 4mm key handle diameter and long enough to slip over both ends. It should be scaled up for a larger Jacobs chuck key.I printed in TPU 95A which is a bit stiff and inflexible but functional for this application. I will try an 85A or 90A.
