YA GM328 Tester case

thingiverse

Here is another enclosure for the BM398 transistor tester. This one houses the battery and holds the PCB in place, exposing the components, LCD display, and other internal parts for easy viewing. Since the PCB fits snugly inside, I opted not to create a separate battery holder, choosing instead to affix a 9V battery clip to the bottom with tape - a straightforward modification that should be simple to implement.
