Dunce Cap

Here it is y'all.
The Dunce Cap.

I made a special cap for the pen, allowing us to install a Screw-It ball to the TiBolt.

Spin the pen
Spin the cap
Sit and Spin, I don't care!

Lot's of folks like dumb things and guess what?
I make dumb things!

(If you buy copper, it will come somewhere on the spectrum between the two in the picture.)
