ASAP (As Straight As Possible) CR-10 filament guide

thingiverse

I'm glad to see everyone here today. I used to swear by Greg191134's filament guide or one of its clones for years, and it worked like a charm every time, so I want to give him credit where credit is due for his brilliant design. In fact, it was my very first CR-10 mod. The problem with the original guide, though, is that when printing with bamboo or other rough, sticky filaments, its relatively small curvature can cause issues - the filament often gets stuck in the guide before even reaching the extruder. So I decided to take matters into my own hands and design a new guide with an as straight path as possible, without touching the greasy bar. And the best part? You can easily add a small piece of PTFE to the mix, just make sure to work it with a round file to open up its entry point and enlarge the outlet.
