Prusa XL - Nut for 30x30 profile

This is a nut I made to fix the scrubber of the nozzle of the heads of my TH5 prusa xl ( https://www.printables.com/fr/model/462473-prusa-xl-series-nozzle-scrubber-brush-update-inclu )

Insert a M3 nut on the side and then insert the nut inside the 30x30 profile. Turn it 90 degrees and then you can fix the tool on it.
