Important aspects indeed, some info were available on the old BOM list, yet it is good to remember them here:
Mechanical assembly:
- Hex keys: 3 / 2.5 / 2 / 1.5 mm (take several 2 and 1.5 size because they are really quickly damaged)
- Small screwdrivers with Phillips heads (M2 & M3 size)
- Threadlockers (2 bottles for a whole Poppy humanoide)
Wire connection
- A glue pistol is convenient to fix some wires where you want
- If you want to create custom wires you will need a wire stripper, some Molex connector and terminals, and a small plier such as this one.
Also you can see on this picture (on the right) all the tools we have used the last time we built a Poppy humanoid:
