Threaded Filament Dust Filter + Knurl = Replicator 1,2 & 2X

thingiverse

This Threaded Filament Dust Filter, designed by http://www.thingiverse.com/thing:153807, has been improved in a remix (http://www.thingiverse.com/thing:258598) with a wider knurl for added functionality. However, I require a smaller version, so I made a recessed knurl design in the first iteration. Despite this, the print failed due to an insufficiently sized knurl. Thus, I created a dual-color printable wide knurl version and also added a knurl to the male part. To accommodate different users' needs, I have also included individual and dual set parts files. Please note that these are large STL files; print settings include no raft or support, 50% infill, three shells, .27mm layers, and a 102% scale for the larger female part in ABS. For optimal printing, use active cooling airflow after starting the first layer, and set extrusion temperature to 220F with a 110F hotbed.
