T-slot Adjustable Angle Hinge

Design for an adjustable connector to fit two 1010 type T-slot rails together. Still at early WIP stage, so some other pieces may change. Most likely putting on some holes for nuts or bolts (needed) and an alternate hinge piece with an anchor base on it.

Yes there's another hinge for T-slot rails, but if you look at it it seems to be for a different application. In this case it's setting the angle for T-slot rails end-to-end, which I think will be useful in other ways.

The hinge itself will be held together with a nut & bolt and some washers, but they're not pictured in the current render.

But the main idea here is to use commonly available T-slot rails as a base for an assembly jig. So this would allow you to set an angle for various parts, while inserts that go into the T-slots would hold various model parts together for assembly and gluing. (Focus on RC or model aircraft stuff.) That's going to be another project though.

And if you like these kind of things and would lik
