modified Idler for the ender 3 v2 all metal extruder

I remixed this from:  https://grabcad.com/library/cr-10-extruder-1 by a user named Mysterious

This is just the same all-metal idler but with an m6 thread at the filament inlet. I printed this with a 0.2mm nozzle, a 0.08mm layer height, and 100% infill. It took a little over 3 hours. I recommend something with a higher melting temp than PLA. I don't know why but I'm having extrusion issues after I added this for some reason. (actually I think its due to warping)

V1: 

If you are going to print this, be aware that the washer that goes on top of the bearing of the idler does not work with this mod, so you need another 1mm washer to replace it. I have a step file of a washer, but I recommend finding a different washer. The hole on the top left also has to be drilled as it is a bit small. It also tilts when all the screws are tightened. 

V2: 

I enlarged the hole with tolerancing issues, but I have not tested it. 

I added an M6 thread on the filament inlet and made it easier to screw in the m3 screw that holds the spring. I also enlarged a hole in the corner of the idler
