A bit of a diversion, but I wanted to see what some laser-cut acrylic shields would look like (first time I've ever made anything with acrylic).
Small top and bottom guards on the main board + 16-chan servo controller configuration (there is enough space between the bottom acrylic and the main board to host a LiPoly):
Also, outer rings that can be stacked to make a solid case:
Here I have the small board-sized top and the rings together (they mount into a full pane on the bottom with appropriately spaced holes). Alternatively, one could just mount the boards on the standoffs without the board-sized top and use a full-sized pane on top (made with this batch, includes the engraving as well, but not shown)
You cannot see it well in this photo but there are also outer rings with cuts for a USB plug to fit in. They can also be oriented to provide access to the two user buttons, but was not done for this picture.
