A simple idea to pick the right screw every time…
You know, these are looking almost the same, but one is longer, in order to let you fix the extenders under the case… (or any accessories)
So to identify them for sure, I just added a small white dot of “TIPP-EX” TM (or from your wife’s French manicure set!) on the longest screws.
Using this simple tip (TIPP-EX? joke inside) I do not make any more the mistake!
Some pics of this are here:
