I also agree with that. Unfortunately, I don’t think this is going to happen in the immediate future (maybe in the next month or so) because of how busy everyone is right now. I know there is talk of offering spare parts, and I know talk of a wiki keeps coming back every month or so.. the will is there, the problem is the limited resources (not enough hours in a day).
@Bruno, There are plenty of rubber pads you can find on ebay or similar, they usually come in packs of 4 or 10 or something like that, so you don’t need to buy the exact same part (should be easy to measure though), you could just remove the other 3 and replace them all with the new rubber feet you buy.
P.S: This is the source for a 3D model I did of the Librem 13 v1 : librem-model/librem13.scad at master · kakaroto/librem-model · GitHub
You can see my measurements for the rubber foot there stating it is 17.5 mm in diameter and 2 mm in depth :
RUBBER_FOOT_DIAMETER=17 .5;
RUBBER_FOOT_DEPTH=2.5;
You can search and find for compatible ones here (as an example) : Shop by Category | eBay
P.P.S.: this does not remove the fact that we need to provide spare parts, I’m just trying to give you a temporary solution.
