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.
V2: Lowered the bottom so the entire dragon heatsink is exposed to the fan, the frame was blocking it partially, causing oozing and stringing often.
The author remixed this model. Imported from Thingiverse.
Combined both things
