I have a 20b Frontalini that I just took apart to inspect and take photos. And now I'm facing my least-favorite part of the process: getting all 10 buttons to go back into all 10 holes.   Anyone got any tip to make this less a pain? My record right now is getting 9 to line up perfectly but just can't get the 10th. I'm trying this laying down on the couch to make it easier on my neck as I try 20 times in a row, and I'm using the eraser end of a pencil to try to nudge recalcitrant button
