I thought I had made a video of how to assemble this figurine but it seems to be missing. Basically, all parts are already printed in the position they should be in. You need to take a very sharp cutter knife or scalpel if you have and detach each part from the scaffolding (marked red). There are two alternative heads. Start by detaching a head, then the neck joint, assemble them, then detach the next joint, assemble it and so on. That way parts won't get mixed up. If you have already detached all parts perhaps the image will help arrange them in the right order. Let me know if you need further assistance.
