I was looking for a case to hold 3 calcium chews for each day because I keep forgetting to take them. I thought this way I could grab a box every day and throw it in my purse so that maybe I will remember to take them. Had to change the size of the original one, add a bigger bump on the inside of the lid (you might have to file it a little so it isn't too big). I was able to emboss the days of the week in 3D building and have also included the blank lid so you can put whatever you want on it.
Print the sliding lid on it's side so it is standing on the long side and use a brim so it stays up while printing - not face down or face up.
