I made this clamp to hold the Extruder release lever when I'm changing the filament, so I don't have to. This was printed and used on the Ender 6 MK8 Extruder, it's a tight fit, I included the blender file to allow adjusting the length if it is too tight or loose on other Extruders.
Between where my printer is and the Extruder being on the back right, it is awkward to get both hands back there for the amount of time it takes to change out the filament. Opposite the Extruder release lever is the tension knob which is hard on the fingers. My solution is this clamp to hold the release lever while I'm changing the filament out. With it, both hands are free to pull filament and rotate the spool. Just remember to remove the lever before printing.
