Just a quick heads up about a great resource for case/box making.
MakerCase is a web-based application for designing laser-cut project cases.
Makercase runs in a web browser and automatically generates a blueprint for laser cutting based on the users specifications. The user enters the desired case dimensions and material thickness, and MakerCase automatically generates a three-dimensional model of the case that can be freely rotated.

A few pictures from my “bits and bobs” case made with the makerscase tool.
Added cut for opening and sketched up the inserts.
