There are some things to consider when doing a 3D design that complicate the project, and for that matter, may or may not render the design "workable".
There has to be at least one flat space that hits the build platform. Modeling a cube standing on a point isn't a good idea.
There's a limit to how much and how long an overhang can be without having a support. Supports can be removed, if done gracefully. Otherwise, the unsupported part tends to sag.
If you use OpenSCAD, then it's a parametric modeler. You can easily specify the basic backplate and the edge as a model. You can base models off this. Adding a hole at a particular point, square or round, is easy. it takes a few lines of code.
Adding a boss on the front, or on the rear, is easy enough, however anything on the rear keeps the back from being flat, and that's a problem.
For material, PLA would be the material of choice to make the initial models. Making them out of ABS or PETG would be a good choice for durability.
Color is not going to be a problem, you can get pretty close.
There are ways of working around some of this, but those ways do make life more difficult.

There are no protrusions on the backside but the inner flat rectangular center of the front panel is recessed on the other side just like the front side. In other words the front panel is reversible.
