1010 Extrusion T-Slot Simple 90 Degree

Just a simple 90 degree fits the 1010 extrusions. I got mine from McMaster-Carr. The dimensions are 25mm x 30mm x 30mm. I have it setup to fit with the standard T-slot screws, 1/4-20, or M6 since I have a mixture of stuff wanted to make sure it would fit for all the options I could think of.
