Replacement Pointer Nub Thing

Açıklama

A replacement cap for your TrackPoint ™ style pointing device (https://xkcd.com/243/). I built this model to replace the thing on my Twiddler 2 because Steve Mann is my idol. This should also fit some old-skool Lenovo, Dell, and of course IBM laptops that use nipple-shaped mousing contrivances. Caveat: I gave this a tall domed top because I'm diddling it with my thumb. If you print this as-is, stick it on a ThinkPad, and close your lid, you'll break your screen. You should download the included SketchUp file and cut a big dent out of the top first. Please PM me pictures of your cracked ThinkPad display so I can laugh at you and add them to the gallery.
