Upgrading the hotend fan from the standard 4010 to 4020 makes it hard to attach the FYSETC Portable Input Shaper, as the fan cover can't be easily attached.

I've created this mount that is a snug fit below hotend and attaches to the aluminum mount.
I recommend printing in PETG as when fitted it's close to the heat block. 10% infill, 3-4 walls. No support needed. Print vertically.

Requirements: 2x M3*8 or M3*6 screws.
Optional: Double sided tape. Put on the inner side facing the aluminum mount to secure.
This is optional - the print is quite tide and a snug fit.

V1: Without the hotend screw hole.
V2: With the hotend screw hole.
