VAIO doesn't sell a replacement clip for the Z Canvas pen, and it's pretty easy to break or lose if you leave it on the tablet. I printed this with PLA, but it would probably be better suited for a somewhat more flexible material. Printed on my Monoprice Maker Select Plus and test-fitted into my Vaio Z Canvas. It goes in tightly without sideways wobble. PLA does not have enough flex to allow the pen to snap in sideways, so drop the pen in from the top.
