This is a mix of the current hotend mount I'm using with a chimney+flag combination mount for the Prusa IR sensor, remixed from https://www.printables.com/model/8808-prusa-mk3s-mmu2s-ir-sensor-mount-bondtech-bmg.
Posting in case someone finds it useful, it's working so far.
The author remixed this model. Imported from Thingiverse.
Combined both things
