This is a double hanger I designed with two mounting holes for # 6 screws in the back. Can be mounted in lockers or closets, etc. I have also included a “keyhole” file to use as a negative modifier in place of the holes (can be applied as a negative modifier in the Bambu slicer) and I would recommend using two of these on each hanger. This so you can mount on any wall surface by installing two panhead screws in the vertical spacing pattern of the “keyholes” and then sliding the hanger on them. Simple mount idea.
