I love a strange keyboard, or a weird controller (here's looking at you Victrix Pro BFG), but I've discovered I might be a bit more traditional about my gaming mouse preferences, if this DIY fingertip mouse is anything to go on. To be fair, it could be the whole 'spider-like mouse where you can see its internals' thing that's putting me off.
X user Pseudoku recently took to the social media platform to show off their mouse, or as one comment argues, spider. Effectively, it's a handful of platforms made out of nylon on top of a traditional mouse's internals, so you can rest your fingers. It doesn't look particularly uncomfortable, but it does seem like resting your palm would be tough, and may jam into a pointy bit.
Have been happily using mine for over a year and now that the hype is dead, I'm open sourcing it on my GitHub. Made a few adjustments on the model, edited my codes to more human legible form. pic.twitter.com/q6ndQ3SDDdJune 11, 2026
Luckily for you, if you want to build one for yourself, Psuedoku has shared the mouse on their GitHub. You can download the STL files to 3D print the shell and paddles yourself, or you can grab the SCAD file and edit it to your proportions. Should you have a particularly big or small hand, it might need some adjusting.
It even comes with step-by-step instructions on where to place the internals, how to attach the different 3D-printed parts, and where to place the battery at the end. It looks pretty good, despite how weird it is.
