20mm t-slot 90 degree joint

Built in support - with such a simple part I much prefer designing in support, then printing with no support in the slicer. I find this uses less plastic, and is easier to remove.
The ridge that sits in the t-slot is continuous between the two rods - guarantees perfect alignment.
The scad file is horrendous - not parametric at all, I just wanted to throw it together quickly.

yeah i tried to print it like straight up, but it got all warped, and then i came across one that had been printed at 45 degrees and realized it haha. if i do need support though in the future i will use your method though.
DOH, that's the much cleverer way to print this. Ah well, it was a useful exercise in designing support.

Snap off the support with pliers or a knife.
Push into t-slot, and bolt in.
I printed mine a little too hot, so I had to slightly file the ridge to get it to fit, and the overhand at the top drooped a little bit, but it works perfectly.
