Great update, it comes in handy. Though for a persons bad review when they say why stick sharp metal up to the screen, you dont need to, its bolts and the flats of drill bits not screws.
Fun sapian
A few fractional sizes, and what that size is in metric (not true metric). No tap and thru holes for screws. Utterly useless.
