New whiteboard pen clip to replace the one that broke this evening. Note the substantial bands—those are not part of the design but rather a printer problem (known as “Z-ribbing”) I am still trying to diagnose.

I did a couple iterations on the design. The last should be substantially stronger because it has gentler interior angles, as you can see in the image where the pen is mounted on the right-hand side of the whiteboard. 1beyz5vitambm.jpg

Another potential benefit: It would probably be better for the pens to store them cap-down. I can tweak my design to make clips sized for the cap instead of for the pen body.
