Here's my print with Prusament PTEG. I still need to dial in my printer a bit, but overall I like how it came out. Very clean shape and design for a backpack hanger.
One issue I see is that the upper two holes are over 1.5" apart, which means that screws won't land on a stud if you are mounting against drywall. I might consider remixing with two screws on the vertical axis, one hole printed at an angle in the upper area (through the hanger portion) and another just a bit lower than the original center hole. That would allow you to land the mount on a stud and prevent twisting.
Super cool model though, and perfect if you are mounting it to a wood panel, etc.. (edited)
