This is a remix of the MK3S+ Hook for scraper tool to attach a 120mm fan to this.
With a M4 x 35mm screw and a M4 hex nut use the version: hex_hook_m4_hole+nut
or just use the 4mm mounting holes and use the version: hex_hook_m4_hole
I also included the .step file with both of them
material: PLA or PETG
layerhight: 0.2 or 0.3
