Rail Aux Part Cooling Fan Ender 3 v2
thingiverse
Aux Part cooling fan for 2020 extrusion rail. made for ender 3 v2 but will likely fit and x gantry rail. May not fit rails using rollers but you could trim the top overhang, works for linear rail upgrades. doesnt add weight to the print head but adds weight to the gantry so dual Z is recommended. Youll need some threaded inserts for the fan screws and some v-slot nuts to attach to the rail.
