A Clip for the Apple Pencil

Render of the Apple Pencil clip

The original Apple Pencil, in addition to its phenomenally bad charging method, has no means to keep it with the iPad. The nice leather Sena case we keep the iPad in doesn’t have a loop for the pencil. I solved the problem by coming up with a clip that’s easily tucked into the case when it’s closed.

This was a quick project, created in less than an hour of CAD work. The first print back from Shapeways had a couple of problems. I made the inner radius of the clip match the pen, thinking it would shrink enough from the spec dimensions to fit securely. Nope, it fit perfectly – and slid right off. The second issue was the original spike was only about 1.5mm thick; turns out that’s pretty bendy in Shapeway’s nylon. For the second revision, I made the clip diameter a full millimeter less than the pencil and it clips on securely now. Making the spike about 3mm across is rigid enough to stay in place.

Ironically, Sena now sells the case with a loop to store the pencil. But it’s still fun to solve the problem in less than an hour of design time. The STL is up on Thingiverse if you want to print one.
