After making two of these, one for me and one for my wife, my wish is that the cap had some kind of clip built in so I can put on my shirt or other location just like a pen. I have no clue how to do it myself as I am just starting 3D Printing but here is to putting the idea in your head.

Thank you for the thing and hope it sees regular updates and improvements.

Also, any idea how one could add a letter to the underside of each piece?
