Extruder lever (better than button)
thingiverse
Pressing on the extruder to let the filament pass is uncomfortable even if you use a cap and I think I've found a solution by applying a principle discovered a few thousand years ago ... the lever. I then combined the lever with a filament guide, getting a good result in my opinion. It's my first improvements to the A8 and can be improved from many points of view, so any suggestions are welcome.
