Fixpencil 22 + Adonit Jot custom iPad stylus End Cap

My go-to mechanical pencil is the Fixpencil 22, which makes working a true joy, yet I've been itching to work digitally on my iPad lately. My second-favorite "pencil" is the Adonit Jot Touch, a really neat pressure-sensitive Bluetooth gadget that's a lot of fun to use. However, my favorite iPad drawing app is Paper by FiftyThree, which unfortunately doesn't support the Jot Touch's Bluetooth features. The Jot Touch has a bit too much mass and momentum for my taste - it's significantly heavier than any other pen or pencil I regularly use. This made me curious whether one of the Jot Touch tips would work with my Fixpencil, and to my delight, they do! The whole pencil is made of metal except for the plastic button on the end, and you can even leave the pencil lead loaded in behind the Jot Touch tip. One thing to note, though, is that the Jot Tips are a bit fragile - not exactly the kind of thing you'd want to expose to the elements in a backpack for weeks at a time. So I designed and printed this little endcap to protect the Jot Tip while it's loaded into my Fixpencil. The OpenSCAD file also includes a simple model of the Fixpencil itself, which you can use to create your own accessories - including an untested parametric model of the end button, as measured by a micrometer. You could print out spare buttons or create ones with different designs using this model, although it doesn't include the lead sharpener part. I'm confident, though, that you could easily make one in plastic if you tried!
