Extruder for flex (Mk8)

This is a replacement for the stock extruder plate which allows to print with flex filaments. I tried on a medium soft Flex-PLA and it works fine for me.

This is remixed thing. My problem was I printed the original thing with ABS. When I tried to screw the fitting, it just cracked by layers. So I added a thead for the fitting.

The fitting have diameter 6mm. But taking in account that ABS shrinks after cooling, here the version with larger diameter - 7mm. If you will printing with filament without shrinking, use version with 6mm. Also you can print _thread tests_ to figure out which version of thing to use.

Also, here is the link to [Tinkerpad model](https://www.tinkercad.com/things/0RTtbvc6USY-extruder-threaded-m6-pitch-1). You can easy to change the model's thread.
