It seems a complex disassembling and I don't feel comfortable with it for the time being ! I have a few questions: Q1: What is the name of the tool shown at 1'47" used to extract some plastic parts ? where do you buy it ? Q2: You take a photo of "the position of some white plastic screws", but it unclear on the video of what position should be noted ? 'the closeup is not close/clear enough) Q3: What is the name of the round piece with a motor that should be bought on eBay / Aliexpress ? Thank you very much for this video and for your skills, but we need a bit more explanations to feel comfortable with it !
