Umbrella Stroller Handle Extension

I have found that the handles on my daughters umbrella stoller were just a bit too short to be comfortable so I made extensions. I originally planned on using 1/2" pvc for the handles so the clamp is sized to allow that. However since I am using a cr-10 I was able to print handles that were long enough. I have been using the handles the last couple of days while on vacation and will probably be making a few changes from things I noticed but mainly just the handle design not the clamps.
