Cutaway Lock - Tensioner

Tensioner for the cutaway lock by zbzzn:

It fits in the rear of the lock, giving full access to the front of the lock for picking. It's not representative of a real tensioner, it's just to provide a way to put tension on the lock without putting too much stress on the plastic core.

NOTE: Despite the appearances, this is NOT a slot machine :D
