Should I bin it?
It takes a good 10 minutes for my mouse (Logitech M180) to come to life, I mean, the left click doesn't seem to work for the first 10 minutes after I haven't used it for some time. Battery is ok, right click is ok.
I blow some air into it... nothing. Then I leave it there for 10 minutes and the left click comes back to life.
You're in a DIY group, and you haven't taken it apart for a look ???
With the old rubber ball mice, they needed constant cleaning of the
rubber ball. Like, daily even.
The optical mice, are pretty well impervious to fuzz over the
bottom optics. However, the scroll wheel, the microswitches
for the buttons, those collect fuzz (or sugar from coffee spills
or Coke) and that can clog up the works.
One failure mode I had, is enough fuzz collected under the plastic
"panel" that is the button, to prevent the plunger on the microswitch
from completely depressing into the switch casing. Simply cleaning
out the fuzz, was sufficient to restore operation.
The metal bits on a microswitch, the plastic "nub" on the panel,
some of these things wear or lose their spring constant, and
the switch failure is related to that. You cannot easily
build up the nub on the button of the panel to make it work again.
If you used epoxy (to make a nub), it would wear down in no time.
And 3D printing... it's going to depend on whether you can get
the right material for the job.
And just for the record, they don't really have to design mice this
way. The fuckers are just lazy. Some mouse designers are pretty good
at their job. The mouse wheel can be removed for cleaning, the slots
(optical interrupter) can easily be cleaned and so on. Then there
are the other idiots, who have never taken apart the industry-leader
mouse for a look, they put heavy metal plates on the side of the
mouse wheel and they don't allow cleaning of the wheel.
I could smack somebody...
When disassembling a mouse, beware. As some mice have an excess of
really really small parts. If this is your first time -
1) Work on a light coloured table top, with a surface that's not too hard.
The tiny shit that falls out, can go quite a distance.
2) Important - move your belly right up to the table. Tuck in.
This prevents the bloody tiny ibeam spring from disappearing into the carpet!
If you step on the point of that in bare feet, you're gonna scream!
3) Mice usually have a hinge on one end, screws hidden under something.
The good mice, have an "X" cut in the sticker, to show you where the
Philips head screwdriver goes.
4) Disassembly the mouse, in the same orientation as you use it.
Like, after the screws are removed (upside down), turn it rightside up again.
Do not turn it turtle and disassembly and attempt to lift the bottom off.
In the "normal" orientation, with some care, you might not even
disturb the scroll wheel, and all those tiny parts that can fall out.
Have fun,
Paul
