Deck holder for sleeved cards

I created this card holder to keep in place sleeved cards when playing games.
I use it for Terraforming Mars.  

High enough (11 cm) to keep a lot of cards.  
Fit well with Mayday games premium sleeves: 63.5mm x 88mm (MDG-7077)

Update 2023-08-06: added a smaller version (height 8 cm), bottom surface sliced in half.
