Securely Attached Wiimote Gun

This is a remix of the amazing [Cooler WiiMote Gun](https://www.thingiverse.com/thing:4582102) with the following two changes:

1. Wiimote power button is accessible when remote is inside the gun
2. A slit below the slide allows the Wiimote to be securely attached to the gun using a rubber band

If you don't have a rubber band that fits, you can 3D print one using the attached STLs. Note that *the rubber band must be printed using flexible filament.*

I've added two models for the rubber band, one that is just a plain band, and one that has a rear sight. You only need to print one of them.
