I just wanted to share this handy tool I recently used to disassemble my Fairphone 3. It has the correct Phillips head size, and also a T5 torx head for disassembling the individual models and the motherboard shield. I am currently travelling and was satisfied with the small size and also the high quality feel of the tool. I found it on amazon, if you want to take a look.
The other bits get stored in the body of the tool, under the large blue cap.
