So, i'm interested in printing in a flexible filament and i've seen a lot of people printing replacement MK8 extruder parts that keep the filament on a better line through the drive gears, ideally i'd like to try the same but i want to print a a simple upgrade that doesn't require lots of modifications. upon looking on Thingiverse i can see many different mods out there but firstly i'm not sure which ones are the best and which ones may fit the Qidi Tech printer easily.

My initial investigations have led me to this one : http://www.thingiverse.com/thing:684426

Thoughts from anyone with a Qidi that has printed with flexible filament.

Many thanks

Steve
