I remixed this: https://www.thingiverse.com/thing:3171895/remixes

Bondtech mini geared remote extruder front part( lid) with hole. 

Visible extruder shaft movement to check feeding.

 and M6 bore pneumatic fitting hole

I have designed a thin (1 layer) membrane in the screw holes to avoid the need for supports. After printing, it can be cleaned with a knife or a drill bit.

First layer arhimedean chords pattern,  roughly polished steel like results (see the photo)
