Sorry to bring this up from 9 months ago but I'm hoping to make a stent similar to this one. I'm curios what you're using as the white cap on the end and how you secure it to the modified catheter. I've been lurking in on this thread for over a year now, its been my motivation for getting comfortable with catheters so i can eventually make stents for myself. (Edit: Nevermind, I see you went into great detail about this design in the "Close To Incontinence With A Catheter" thread.)
