Pretend that the TiBolt didn’t already have enough Fidget Factor.
What would you do?
Add a spinning cap of course.

Here we have the F.ellhoelter A.ccessory P.en Cap, or FAP Cap…
This is a nifty little spinner, running on a hybrid ceramic bearing.
I’m making them out of several different materials, with a few different mounting options.

These replace the standard cap on all of my pens and pencils.

The spinner itself is interchangeable, and can be removed and cleaned when the bearing gets gunked up..
You can blow it out with compressed air while it is mounted, or take just the spinner off with one screw, and clean the bearing with Alcohol, Acetone, or Brake Cleaner.

The spinner on a short stem adds 5mm to the length of the pen, 6mm on a flanged stem.
