Voron 2.4 (or any other) 2x120mm controller fans in bottom panel

Put painters tape on the panel and then use the mount to sketch the outlines onto the painters tape. Use a jig saw to cut out the holes (with some extra room around it, be careful to not get to close to the holes.

I melted heatset inserts into the fan and used M3x8, you can also use longer M3 screws and nuts. The screw head holes are sized for M3 SHCS.
