As Flux users know, changing to and from the print module involves detaching the filament feed tube.
I've given up trying to undo this at the top connection point and even unscrewing it from the module I've found rather a pain so I've designed this nut/tube spanner to make the job heaps easier.
Designed in Moment of Inspiration (Moi) and printed on a Robox in Robox ABS.
I used 6 layers top and bottom and perimeter.
Material Robox ABS.
Normal clean up.
To use, firstly place the nut/tube spanner into the hole in the top of the module.
Then push in the tube and turn the nut.
