Alternative case for the HP-41

[Kostas Kritsilas]

There are a number of sellers on eBay that sell cases for Fluke meters, in both softshell and hardshell versions. Usually, they have a pocket for probes, but I am sure that they can be used to hold quick reference guides or magnetic card packs. You just have to be careful that the interior measurements match up with the dimensions of the calculator you want the case to house.
