Flashforge Filament and Wire holder for 1/8 NPT

I really liked this one http://www.thingiverse.com/thing:735350 but the push on fittings I had were threaded for 1/8" NPT so I modified the original to reduce the hole size a little. I then drilled it out and tapped it to put the 1/8" NPT threads in there. Maybe someday I'll try to add the threads directly to the object. I used these connectors https://www.amazon.com/dp/B00A150R3O/ref=cm_sw_su_dp.
