I had a new custom dash made for my Harley, it arrived today. To install it you need to tighten up a Chrome Ring that is actually the fill for the fuel tank as well. The manufacturer states that you just hand tighten it and it will be good. Well I tried that and there was no way for me to get it tight enough to mate the parts correctly.
So I got thinking where can I get a tool fast enough so that I can install this part and be confident it stays in place. Then I decided that I would design a simple tool with Shapr3D and 3D print one. If I give the printed part enough shells and infill it should be strong enough for what I need.
After printing it, I placed it inside the chrome ring, turned it tight with an adjustable wrench and put the fuel cap on. Another real life problem solved by Shapr3D.
In short thanks to Shapr3D I was able to design, print and install my part in less than 2 hours with confidence that it will remain in place.
