Ender 3 extruder clamp/limiter

I designed this to help with changing the filament by clamping/pushing the extruder of the Ender 3.
Installed and tightened it will let the filament run smoothly in between the extruder wheels for insertion.

Also I think it should be possible to use this to print soft filament more easily.

In theory you can adjust the spring force of the extruder clamp to not squish softer filaments.
Though, I haven't tried that yet.

Watch out for the fitting of the M7 screw. I printed the Screwknob
