I made this and thought that it looked cool, to make this you will need two m3*30mm bolts and two m3 nuts Along with the two STL files there is a STEP file incase anyone needs helo and an instruction manual wich you can download. I can adjust the angle so it should work for anyone else. 

If your printer doesn't have the best tolerances, don't worry, I have included 0.5mm on each side of the upper part but, i would also print the two parts slightly bigger to leave room for the screw to go through the screw hole! 

here is the instruction manuale incase anyone couldn't find it:
