Card holder 3 rows and 2 rows

Since the kid enjoys playing cards so much but can't hold the cards yet, I designed this multi row stand. The single stands available are to small to holds multiple cards.

I've created a 2-row and a 3-row holder for the cards with a base size of 18*18cm and therefore it can be printed on a Prusa Mini or Bambulab A1 mini as well.

I've uploaded the STL and the 3MF file to print.

You can print this model support free with little infill (I've used 10% infill with 5 top-layers).
