GM328 Transistor Tester Case

thingiverse

The enclosure is specifically designed for the GM328 transistor tester, with a PCB that simply closes the box, allowing all components to be easily visible without any cover. To power it, I used a battery from a power bank, paired with a TP4056 charging module and an MT3608 DC-DC converter. A 10x15 switch was also incorporated into the design, along with stands and screws taken directly from the tester itself. However, the stands proved to be slightly too tight and required some gentle heating to set them properly in place - for this task, I relied on my trusty soldering iron.
