USB Flash Drive Cap

Certain slim/key sized USB flash drives are prone to the metal casing bending and "bowing" in. I created this end-cap in an effort to reduce the chances of my Kingston DataTraveler SE9 Gen2 drive caving in.

There are two versions:
SHORT - outer wall is 7 mm tall, inner tongue is 10 mm
LONG - outer wall is 12 mm tall, inner tongue is still 10 mm
