This is an accessory holder template that is set up to be adaptable to fit a variety of fixtures, mounted on a 2 piece pipe clamp style ring that fastens together with M3 screws to mount on a vertical pipe, pillar, or tube shaped support. The inner diameter is 100mm, however this can be successfully scaled up or down a few % without affecting functionality negatively. I used it in combination with a heat gun holster by simple merging the two models in Bambu Studio. The possibilities are endless for what design you want to merge this with and mount on a pole.
