This organizer is derived from @amyjo88's very nice design. The main differences:

• The tower dispenser is modified to make the front slide into the base. That makes it easier to reload the dominoes and doesn't require glue.

• The QInsert1 part was too small to hold all the building tiles, so I increased its size. The other components of the organizer were adjusted accordingly to accommodate the differences. 

• The QTray was meant to be stacked but the dimensions were wrong. In this design, two QTrays can be properly stacked on top of each other. 

Print two copies of the tower components and the QTray, and one of each QInsert1 and QInsert2. I recommend using a brim to avoid warping. No supports needed.

I uploaded several versions of the tower front with the crown. A simple debossed crown; an embossed crown to use with a manual color swap; and a flat version for use with a multicolor printer such as the Prusa XL or an MMU. See 3mf files for suggested print profiles.

I don't own any extensions so I'm not sure if everything fits okay beyond the base game.

I strongly recommend @Julius3E8's castles!  https://www.printables.com/model/248828-single-print-queendomino-castle

I also hate the tiny "tax collector" knights so I replaced them with my viking meeples https://www.printables.com/model/22204-viking-meeple
