Flexible Filament Extruder For Ender 3 With Direct Drive Mod

Print out the new extruder before removing old one, and check all bolt tolerances before assembling. I remixed because the original two designs I based it on (and every one I had seen) were not built to fit my direct drive extruder. I wanted to print TPU, which I have, but the current extruder keeps jamming. So I threw the files I remixed into Tinkercad to extract part dimensions and rebuilt the part from primitives even better I'd argue than either original file had done. I can't get Thingiverse to credit the original designs, but here are the links for those interested:

Update: added V2 with support included so you can print with support touching buildplate instead of everywhere
Update: added V3 with looser holes.
Update: It finally generated a preview, but only of the obj I used for rendering. The obj preview looks corrupted because it is smooth shaded for some reason. stl previews are flat shaded. So if you didn't know, now you know. I learned this from trying my hand at rendering. Unless your design has a ridiculous number of polygons use flat shading.
