3/4" emt to 3030 extrusion corner

3/4" emt to 3030 extrusion corner, this was started to aid in the build of custom 3D printer. Using ¾" emt tubing and 3030 extrusion to help cut cost, using the 3030 extrusion to run vertically to mount linear rails to. This project fell on the way side, but thought maybe someone else could use this part.
