Right now, and maybe the past decade, the head of my dip stick has been broken off. I can still use it, but it always looks like it might be sucked down the tube and lost forever. I don't think it would cause a lot of damage, but with my luck it might cause the entire car to be immobilized.
For the past few years I've thought that it would be pretty cool for the handle part, which was plastic to begin with, to be in the shape of the manufacturer's emblem. I don't think this idea / product is out there. I've done a quick couple of searches, but haven't found what I'm looking for.
Some people would tell me there is a reason this product doesn't exist. They'd say, "Why would anyone buy a custom dip stick ?"
"Have you seen the things people will buy to customize their ride?" is my answer.
I'll start by making a 3D printed one for my car. I can offer them for every manufacturer, some models, any color, and eventually in metal.
I hope it's a great starting point.
