SONY Memory Stick Holder

This is a case I designed for holding my Memory Sticks I use for my Aibos.
The scale should be correct, it was modeled in mm. It allows for a little wiggle room.
I do not know if it will be usable with Duo sticks or any other model, I use the long sticks and know it works.
I didn't print it very pretty as I didn't know if it would work, but it does, so I'd preferably print it in a black filament instead.
