I needed another corded mouse and this time around I thought of @PKL@mastodon.social and @pronk@mastodon.social instead of Logitech's shareholders. These guys make open source mice among other open source hardware under the brand Ploopy. You can order one from them, assembled or as a kit, or you could print and build it entirely by yourself.
The mouse itself is pretty great. Coming from a long line of Logitech (MX518/G5/G500/G502), it's a bit larger than what I'm used to but I think I'm getting accustomed to it.
Here's another shot of it:
Most slicers allow you to mirror parts very easily
The PCB doesn't look ambidextrous. Maybe there's a way to mirror that too but it's probably not as easy. And you'd have to get it custom built.
Ohh OK, yeah that would be tricky unless you're an EE
