Just another remix for the original Creality mk8 extruder / feeder
reusing 3 of the original m3 bolts, the spring, as well as the bearing 11mm (+/-1mm) OD
-some cheap tube push in fitting (1/4" -> picture above)
!!use a lighter to preheat the hole before srewing the push fitting into it!!
(or just use a 1/4" screw tap, if you have one XD)
-6mm OD bowden tube (4mm ID)
-M3x30 + M3x15/20 + 2x M3 nuts and some washers
-maybe some m6 drill
08.06.19....Also check out the 1.75mm version REMIX by cron1c ;)
16.06.19 .. printed some stuff with it .... and realized i had to use a 4mm bolt for the
bearing... edited it and uploaded/replaced the file ... also added some more
space for the bearing to move --->> the extruder/ runs even better now =)
16.06.19 sent a pm to cron1c .... the 1,75mm version edit is otw, too!
01.07.19 printed a lot of different objects, by now..... all of them using this extruder.
works even better than i expected, as well as any other extruder/feeder I tried
before... TPU and soft filament works fine, too!
16.07.19 realized some problems with the PTFE tube lately... it's beeing pulled back into
fixed the problem, using some hole rivets, which are pressed into two short
PTFE tubes. those are put into the "inside" of the extruder. (6mm holes and the
path to the gearwheel)
one hole rivet sits under the bowden coupling and one is placed where the
filament enters the lever. this also adds a nice, durable, metal inception to the
22.07.19 the "arm" broke in half ... redesigned it to be more sturdy-> vers. 2.2
random PLA works fine for me ;)
Print with 3 outer perimeters at least
