Cubical Mounting Hook

Fourth revision of a generic hook to hang light hand tools and art from my office desk. There are these 3mm wide holes on my cubical walls that weren't being used so I took some measurements for this project. I used a 0.71 inch by 0.71 inch to press fit with mounts or other things. Printed at 15% infill with 30% density on the support materials. If anyone has design tips on how to print this without supports let me know. Remember to make your print grain line up with the load. The gcode is from my Cura 3.4 "lulzbot" slicer.
