Securing and Strengthen Case Halves
This section is relevant to whether a case has been made by vacuum forming or using tupperware boxes, in both scenarios you have two case halves which need not only strengthening but also securing together.
There are various ways to achieve this result, however the one highlighted in the document below is neat, tidy, strong and also needs a minimum of space inside the case to work.

Using “H” shaped tough plastic grooves.
Using “teeth” to secure case halves together
This is a far better solution, gives a very neat effect.
