Hi Trent,
Here is my 3000th post, so hopefully it says something worthwhile.
If your requirements are very simple, then guided by the injection molding factory,
you might be able to stick to just a few design rules.
* Make the walls a uniform thickness, the optimal dimension of which would be advised by the factory. Thinner is easier than thick.
* Radius all corners inside and outside to at least half of the wall thickness. This will help flow.
* They need to easily eject the part and what can help are generous draft angles.
The factory will advise, but if you can get away with somewhere between
1 to 5 degrees for the sides, it would probably keep them happy.
If you create a 3D CAD model and then make a 3D print prototype with the above in mind, you will be part of the way there.
