GM328 Transistor tester case (Original screws)

thingiverse

There are numerous versions of this transistor tester out there, making it difficult to pinpoint an exact match for mine. In true DIY spirit, I decided to create my own custom case instead of searching for one that fit perfectly. This case is specifically designed for the GM328 DIY Transistor tester, and you can compare your version with the images provided to see if it matches. There are two variations of the top casing: One option (3mm Top) features a design similar to the image shown. It requires 4 M3*20mm screws due to an oversight in my initial print, which resulted in a slightly larger screwdriver size. The second option (Original Screws Top) is intended for use with the original screws provided in the kit. To assemble it, you'll need to pre-mount these screws between the top and the 4 lips, then pass your screwdriver through the top holes, as depicted in the image. All of the GM328's features are retained, including SMD testing capabilities. However, battery power is not included in this custom case design. A simple solution would be to drill a small hole on the side of the case to accommodate a battery.
