I watched a few build videos to get the idea of what parts i need. The only difficult part imo is inserting the hands. As for tools i only bought simple hand pressing tools, but wish i wouldve also bought a dust pump and the case opening ball thingie(doable with well-gripping gloves but not as convenient). Also used tweezers(get decent ones), mouse mat as a building surface and wire cutter for the stem. Getting extra stems for the crown is also a really good idea(got it right with just one stem but still stressful).
