Anet A6 Bowden Extruder

This design was inspired by similar designs on thingiverse but modified to suit Anet A6. It improves the extruder resolution by 3.75 and the extruder steps setting will need to be increased by that factor before fine tuning.

After printing and during assembly the guide arm part may need adjusting (filing/scraping etc) in order to ensure that the hob makes good pressure on the filament - after cleaning the holes etc. my unit worked without any adjusting. The spring is the original A6 spring.
