LCR 4 Case - simple, large clearances, no supports

There are a large number of cases for the various versions of the LCR tester on this site already, but I couldn't find one that fit what I wanted. This version is a simple design, with rounded edges, which is screwed together, and can be printed without supports. The battery compartment doesn't require tools to open, it is a spring that can be squeezed to insert or remove. The holes are designed to take countersunk screws and sized to allow thread forming using #4-40 or 3mm screws. In searching through the other available cases on the site I saw common edits and comments referencing small variations in the ZIF socket size or position, and the overall dimension of the board differing by ~2mm. I therefore built in large clearances in the design so that different variants of the board should hopefully work. As printed the battery will be loose in the compartment, I added a piece of foam tape to make it snug. A mechanical clip wouldn't have worked well in this design. With the intended print orientation, the bending stress would be applied across the layer lines making a feature like that too prone to breaking. If you don't have foam, anything ~3mm thick and compressible will do.
