This is my insert for wingspan / Flügelschlag for 1 to 4 players as that's the player count I play with usually. It supports vertical storage but doesn't fit sleeved cards.

I'm hoping that the remaining continent expansions fit as well. I'm especially looking forward to the solo expansion. There's room for more bird cards and regular cards. The egg drawer can probably be cut in half height wise to fit other tokens instead.
The wooden bird feeder dice tower i have is from e-raptor but the cardboard version should fit too (it's slightly smaller if I recall correctly)
