I love 3DBROOKLYN's original SD Card Mountain. It's an excellent and beautiful design.

I have two printers and prefer to use different SD cards for each. I also have more than 5 SD cards. Therefore I've remixed the original design to:
1) Mirrored - so that the cards stickers face towards you.
2) Embiggened - so that it will now hold 10 SD cards, spread over two tiers.

Enjoy.
