This case securely holds and protects a Sparkfun Tinker Kit. It could be repurposed for other hardware, the locating pins that hold the main board will hold anything with an Arduino form factor.
The model I've uploaded has no graphics so that you can add your own. Please see the pictures for an example of how I branded these for my local community college.
The lid is fully removable to serve as a parts tray or can be stowed under the tray. The lid has a detent to hold it closed. The detent is fairly secure and can pass a shake test but is still relatively easy to open.
