I resized it to be 82mm high x 27mm wide, adjusted the threads to make it easier to open and close, and added a ring for attaching it to a carabiner, keychain, etc.
Scaled it up to approx. 125% to fit a folded A4 paper. Great print! Only issue was that the lid went haywire with any attempt to change its dimensions, but was easily fixed with a right mouse click on the model and select Fix, on the build plate.
