another_ extruder

thingiverse

Another extruder? Why? I designed this because I had one problem or another with the existing extruders. The pusher was difficult to thread, the wire often got stuck in a gap, and the extruder fell apart during dismantling etc. So it was decided that it had to be done differently. It's a bulldog extruder, you can insert the wire without any major hackers, you can use existing ones Use conveyor wheels (Diameter 11mm, or MK7) and some different ball bearings. Slider M3: 1 piece V-groove deep groove ball bearing V623ZZV 3x12x4 2 pieces of washer dia. 3.2; DIN 125; above and below the ball bearing 1 piece flat head screw M3x10; ISO 7380-1 or similar .. Slider M4: 1 piece U-groove ball guide bearing U604ZZ 4 * 13 * 4 2 pieces washer Dm 4.2; DIN 125; above and below the ball bearing 1 flat head screw M4x10; ISO 7380-1 or similar Slider ball bearing: 1 piece ball bearing 8x15x5 (MK7) for removed conveyor belts (see picture) Attention!! Print the area of the ball bearing with an infill of 80% you need for all variants: 1 piece of spring diameter 7.8; 18lg (see picture) 1 piece flat head screw M3x10-12; ISO 7380-1 1 piece of nut M3; DIN 934 2 countersunk screws M4x12 All sliders have an M6 tube connection. All components should be printed with Fine (.1mm layer height), except for the tensioner, which has this doesn't work for me. Since the extruder is screwed into one part with the two M4 screws, you can So keep it as a spare part and replace it as a block if necessary. The individual parts should be printed with an infill of approx. 40%. You print the slider M3 and M4, through a Print trick without support. It's a little fiddly with the two washers on that Ball bearings but it works. All parts, except for the slider with conical threading, were printed out and tested several times. I am sorry that there are so many files and that the download in one piece does not seem to work.
