Hi crunchtime2k. Thanks for your feedback according my extruder design. The inlet/outlet areas can be made closer easily by changing only one value in the OpenSCAD file. Please open the file and look for the comment line "// middle cutout for drive gear". Continue two lines after this comment and adjust "cylinder(r = 11.25 + extra_radius..." to "cylinder(r = 6 + extra_radius...". Change the radius according to your needs. Please note, that you have to add proper support via your slicer software.
