For reasons not relevant here I have been using my computer mostly from bed for years now, with the keyboard on my stomach or, when I'm not actively using it, on my side, still on the mattress, or on the floor propped up against the bed frame.

Problem is that apparently it has fallen from that position one too many times and now a group of keys only reacts to key presses if I'm lucky (probably a broken trace somewhere that can still conduct if the stars align to make the broken ends meet).

Given this accidential abuse, it has survived remarkably well. It was a Roccat Skeltr that a former roommate didn't need anymore and gave me when my previous keyboard died, some 8 years ago or so.

Unfortunately, I can't just buy the same thing as it stopped being produced years ago (I tried years ago when the headphone jack on it died).

So my question is, does anyone know of a similarly sturdy keyboard or one that's even sturdier? ISO 105 if possible, either with de_ch labels or else with no labels. Function keys for volume and media control would be nice, but not necessary.

I once tried making my own (wanted to swap the positions of numblock and arrows/Ins/Home/etc.), but soldering the PCB was such a disaster that it was threatening to break just from mechanical stress between faceplate, key switches and PCB alone, and finding a 3D printer capable of printing 45-50cm wide prints for the case in any maker space in the region was a bust.
