Amazfit Stratos Stand - origina dock enhancement

If you use original Stratos dock - docking process is painfull. Cheap chinese docks are not reliable. That is why I designed my enhancement for original Stratos dock.

Assembly instructions:

a) After the printing and assembling enhancement dock check first how it holds Stratos locked.
b) If OK - then take original dock and try to press into the enhancement. If you can't just shave a little of the edge inside the enhancement dock. But usually it is enough just to bend it a little along the longest side. No glue needed.
c) Try again to put and lock Stratos in the original+enhancement dock combo. Check that there no gaps from the arms to the stratos arms. There shold be no gap vertically. In other words they should press Stratos to the dock.
d) If no gaps- (This is INREVERSIBLE, blame yourself if you missed something) then cut 4small grips (tooth) on the original dock as they are no longer needed.

That is it. Other parts used are below. And if you happy with the result - you can leave me small donation on paypal: slibbinas@gmail.com

But personally I do not recomend use cheepos. And this one will not give you slide and click feature, it will not work as with original dock.

Tried SIKAI dock from aliexpress do not fit my stand. Surprisingly it is slightly higher and taller. I was lazy to redesign my dock and just shaved some plastic from SIKAI.
