There’s some OSH designs for trackballs and “ultra light weight gaming mice”, not much for the more standard stuff, just like with most mech keyboards, which are primarily for enthusiasts, often with “deck flex” for a “softer bottom out feel” (and shorter life).
Or just buy 4-5 now and last the next decade.
Shame there’s no a mechanical mouse movement to create an industry of high quality alternatives we can buy.
