Old style phone handset

Fiance needed a prop for a piece she was choreographing. Turns out, there's not really an abundance of 'old style' phone handsets out there (that aren't behind a paywall), so I took a stab at it in Solidworks.

There's a slot to accommodate a standard handset cable (NOT the connector)

Pardon the picture quality...black phones + phone camera + flash = not great.
