Toploader and Sleeve Holder for Cards

My father showed me a tik tok of someone who made a design similar to this. They do not have their STL file available on the internet, so I modelled one myself and printed it.

The geometry is simple. It slots toploaders separate from penny sleeves, but keeps it all in one shape.

I do want to revist this design and see if it's possible to make it use way less filament (maybe a hex pattern in the walls).
