We have a little whale cover for our bathtub spout to protect baby from hurting themselves if they bump their head on it. Problem is my fat fingers can't pull up the diverter knob anymore, so I made this quick simple thing to slide under the diverter pull knob and be able to pull up on the tab instead of trying to dig the knob out of the whale blowhole.
After a few days, I did a re-design and made a new version. The first issue was I found I still didn't make the pull tab tall enough, so it was still a little difficult for me to pull it up; the second issue I found is that it was sometimes sliding out because I was pulling up at an angle from just one side. Enter version 2... This one is taller and comes up on 2 sides so that you are pulling up evenly on both sides. I also decided to bridge the gap between the 2 pulls to make it an assistive device should anyone find a need to pull up the diverter but is unable to grasp the knob. (It's also helpful for me too)
The original thingy is the little yellow tab in the photo.
The Version 2 thingy is the blue pull in the photos.
If your printer is not tuned well enough to bridge gaps, you may need supports, I did not.
