This 24-paint tray and mixing palette with 6 mixing wells is meant to replace one side of the 12-paint watercolor travel set (the side with the paint tubes) sold at Hobby Lobby and Michael's. As these paint cases are made of wood, the insides are not very precise. So, you may need to scale up or scale down the models based on your case. I recommend measuring the inside of your case before printing and scaling down by 1%.
The 24-paint tray should go into the box first and the mixing palette will sit on top allowing the case to easily close for storage and travel.
