I wonder if there is a way to crowdfund actually producing a batch of these? I mean you'd need to redesign the shell and a few more things, but ought to be doable. Either as printable STLs in TEP or as a group-buy. Also, I think it's criminal for any USB chargeable mouse to not just work as a regular corded mouse when plugged directly into a PC. PS - would it be possible to make a mouse use Cherry MX hotswap switches…
It's a lot of organizing work mostly if you have the design ready for a factory
