My second upload to thingiverse - a Playing Card Box that I printed as a christmas gift for my dad (an avid Bridge player)
A friend bought some playing cards with extra large symbols for a grand parent, but the cards came without a box. I volunteered to design and print a box for the cards. It turned out so beautiful that I decided to print a couple more to give to my parents as well :D
I wanted a snug fit to the cards so I just added a millimeter or two on the inside to the box. I went for an even tighter fit between the box with the actual lid so I designed it without any spacing what so ever. This means that you probably need 2-3 minutes of sanding on the surface that connects with the lid depending on how well calibrated your printer is. I prefer it this way since you can decide yourself how tight of a fit you want.
To make sure it could be opened easily I put a spacing of a couple of mm between the lid and the box so that your fingers has something to grab a hold of when pulling it apart. It also makes the design look so much better.
I uploaded two versions, one for poker cards (88x62.5x17.7mm) and one for bridge cards (89x58x16.5mm). The inside spacing is ~1mm on each side of the length and width of the cards if I remembered correctly. The height is a lot tighter though, only 0.1mm for the poker version, and I recon something similar for the one bridge version. It all depends of course on how many extra cards your deck comes with (jokers and such).
If you want to customize it yourself or change anything, you can find my OnShape design here:
The spade symbol is not created by me, but I converted and imported it to OnShape in order to use it.
The credit for the symbol goes to icomoon at flaticon.com:

It's not a complex print, so infill if you want for a few layers on the bottom or just print it solid. I used a brim to make sure the corners didn't warp up from the build plate. If you have that problems you can do the same, otherwise just skip it :)
Some rotation of the lid might be necessary as well to get it to rest flat on the print bed :)
2-3 minutes of sanding the surface of the box that connects to the inside of the lid since it is printed without any spacing. Sand a little, try to see how it fits and then decide when to stop or continue depending on how tight you want it.
I also sanded all edges for a minute or two so that they were smooth to the touch since I printed using a brim.
