- Get a caliper and something to take notes
- Find biggest parts and split them mentally in cuboids, the less cuboids, the better
- Keep one point of your object as reference (one point that will touch the case is nice)
- All the connectors, jacks, plugs and parts that will be accessible from outside, should pop from the internal representation
- Screw holes also will pop as cilinders from your internal model, remember to use the point of reference to make all the positions match with the case's
- Componentize all the parts as a minimum of 2 components (internal+shell). In this case I am using 2 shells
- Draw the shell using the internal model as your reference for everything, it is really easy thanks to the simplified internal model!
- Duplicate your model with the shell components opened and make final touches! Check often the assembled copy you left to keep the consistency
- Print it!
