Thanks to sneakypoo for the original and the effort expended to create it. I needed something larger to hold a standard gift card, and this is the res...ult. The upscale factor in x and y is 2.6x with some reduction in the z direction. Original creator's size is 23 mm inside diameter, while this one is about 60 mm inside diameter. It's pretty darn big when it's done, but holds the cards easily. There's room for a quantity of gift cards or as I did, a card and a 3D printed trinket. When the gift card is used up, it's a pencil holder (2) or other caddy for the desk. Hide your candies in it and keep prying fingers from getting to your stash.
Per a commenter's suggestion, I've added a modified lid which has a 3 mm x 40 mm coin slot, allowing this to become an easily opened (relatively speaking) coin bank.

How I Designed This
Mod...ified in Meshmixer
Simple process, loaded the models, increased the scale in X/Y and reduced the height. A couple slices across the opening to print tests to ensure it would sleeve properly, and awaay we go!
