Hello,
The situation : my Max2 in my backpack as every day but with some more things as usual. I'm walking fast ... the backpack opens himself and the Max2 fall

The first picture is clear. The dust enter in the Max2, the motherboard moves
How to repair the Max2 ? As usual : "Booxtor

". Thanks to
https://ereader.store/en/ for the rescue
Now, what to do ?
I have an other contrainst, I must travel with my Max2 and take it with me in motorbike

The small sleeve can't do the job.
I've try to use a 3D printer, but the Max2's size is very big.
A simple box with a sheet of steel ? Yes, easy to found someone to make it. But before to pass the order and pay, a remark is done on the box'sweight. Only 2.8 kg

Forget it !
Replace the sheet of steel by a sheet of alumunium. Yes, but impossible to find someone able to weld the aluminium
The solution was :
https://www.pr-zinc.fr/ . I've now a box in zinc

You could look at the pictures. The front face and rear face are reinforced with a thin sheet of aluminium. The weight is 1.8 kg. It could be a problem, but a very small problem than a drop for me.
