This is a simple drill chuck key strap (made from Ninja Flex) for a small drill press. This should work on most brands of presses.
Made from Ninja Flex...will not work with PLA or ABS
To make assembling the chuck key strap on to the chuck key it helps to heat the strap with a heat gun or hot water to make it stretch easier.
Many / most corded hand power drills with a keyed chuck come with a rubber strap to retain the chuck key to the cord. I used Pro E to create this strap that hangs the key from my small drill press at a convenient height, out of the way and is stretchy enough to allow for easy use.
