Recommend a material?

[geoffbrown]

Hello, I need some help choosing a finish material. I previously designed and ordered a kite connector as a rapid prototype abs plastic. The ABS part worked great to test and build the item.But now I'd like to find a stronger material. Is there a cast ABS part that would be better or perhaps a different plastic? Any help would be greatly appreciated. The connector is 3/8" thick and about 3/4" tall by 3/4" wide. I've included the drawing below.

See menu Job | Materials and check the Strength fields. But sometimes it can be more economical to use a lower cost material and beef up the design.
