Two Part Raspberry Pi Case

Step 4: Model finishing

The two parts of the case fit together by locating the six pins in the 'lid' part into the six holes in the 'base' part.

As with any type of prototyping, there is bound to be something you haven't thought of. In my case it was not taking the material shrinkage into account.

It was necessary to open up the 6 mounting hole using a dremmel. I used a 2.5mm drill bit to make these holes a little oversized.

If I were to make this project I would have used small screws because it makes the box easier to get into whilst still being secure. Why did you opt for pins as opposed to any other fixing method?

Screws would either involve using wood type screws which cut their own thread as they enter the material or using a tap to cut a thread or using a nut a bolt arrangement. I wasn't confident that any thread in the 3d printed material would last very long and using a nut and bolt would be quite awkward.

Besides the raspberry pi was made for hacking :) so I think the lid will be getting removed and replaced quite often, constantly removing screws would get very annoying very quickly.

If anyone has a different idea for the fixing mechanism I might implement this in case 2.0

Nuts and bolts can be made far less akward by having a hex-shaped slot the nut fits in. That way there's no need for a wrench or some holding method while screwing it in.
