The author remixed this model.
Remixed from @BFBulletMagnet's design to print vertically with no supports. You can use supports for the bolt holes. I did not with no issues. I shortened the hook a bit so I could slip it over with some force instead of removing the bolts. I also removed the graphics. Sorry. They looked cool but would not print very well on my printer. The bolt holes could be weaker printing in this orientation Hopefully the extra material will make up for that.
