Hand Held Products 71 M/M Module Holder

[twoweims]

My design has no latch mechanism like the original. There are tabs at each end that keep the two halves in registration with one another. Some sort of tape could be used to hold them together but I don't use any. When the module is in the calculator the back cover holds the module halves securely in place and when it is out the cover holds them in place.
