Extruder guide for Ender 3.
Simple and prints quick, under 2 hrs for both parts.
Clips to roller spacer and can be adjusted (rotated) to align filament to extruder inlet.
Adjust and secure with screw and washer. The model with clip and no hole has not been tested.
Screws shown are #4. Holes are .1 dia. can be just threaded in.
Bearing is .4 diameter I had laying around. Probably from and old disc drive.
Can be printed without bearing and just use screw and washers or use your own pulley.
(Update) Added flmt_guide_one_piece_3.stl that prints as one part with bracket and pulley and a few other changes. Jpeg image shows printing orientation with supports touching build plate, at 15% fill. I put a small rubber band to help pinch the clip part. Small screw or other methods will work also.
