Filament guide for JGAurora A1.

thingiverse

I was having trouble with soft TPU looping out of the extruder and causing my prints to fail, so I created this guide. Keep in mind that there is a hole for some 4mm PTFE tube; without an insert, the filament may have room to knot up inside the guide and jam. The best plan for the tube is to cut it off square, then insert it into the hole. After that, cut it off as level as possible with the guide. It won't matter if it's not completely flat because there is some space under the bowden fitting. Note that the STL is a little different from the picture I posted. I had to enlarge the guide and this caused it to get in the way of the filament tensioner (it's still loadable but it does interfere). This issue has been fixed in the updated STL.
