Darex M5 drill sharpener, small chuck strap

This replaces one of the plastic straps on the chuck swing fixture on a Darex M5 drill sharpener, which have become very brittle and prone to breaking with age. This model is just the small, inner strap. For the large, outer strap, look here: https://www.thingiverse.com/thing:2877810

Darex part number SA03008PA (that seems to include both the large and the small straps)
