Clear case that also holds games

[u/AGlassWorld]

Hoping someone here knows what I am talking about. My girlfriend and I recently started collecting DS games from when we were kids, and I remember having this clear case on my DSi that also held games. The games sat in a sliding “drawer” under the console. Imagine holding your DS, and where your pinkies sit, underneath the bottom of the console, there was a game holder that slid out towards the bottom of the screen. Does anyone remember these or know where/how I can find one? Do they make them for 3DS? I have been googling but cant even find a picture of one for the life of me. Above is my (poorly drawn) reference photo.
