Sidewinder X1 - Mount for Biqu H2 Extruder

thingiverse

I designed this mount for the H2 extruder a while ago, since there weren't many options around. (NOTE: in the pictures is depicted a prototype, which differs just a little from the final design) It slots securely inside, guided by the two indexes that should easily make the stepper rest against them. The extruder body is fastened by four M3x12 screws, two above and two below, The side bracket holds the stock breakout pcb via a couple of M3 screws which thread inside brass hot inserts (in the pictures i used pressed-in m3 nuts, it's an old prototype). In order to assemble it you can follow the pictures (hoping thingiverse doesn't screw the order around): the mount is to be fastened on the carriage plate with M3 screws (pay attention that the screws don't poke outside on the other side, scratching the extrusion, in case use shorter ones), then the extruder slots in ang gets screwed down, then the pcb is secured. Lastly the fan ducting can be mounted along with the probe (i am currently using this https://www.thingiverse.com/thing:5158514 ). I printed mine in Fiberlogy PCTG, in order to give it enough heat deflection in the case i'm going to enclose the printer. If you don't plan to enclose it, regular PETG should be just fine, just remember to slice it to have some strenght, so to give it at least a couple of mm on each side. I don't recommend printing it in PLA, as it might creep over time, unless you know a really strong PLA blend that you're sure can whitstand heat and load. On the left side I added a protrusion that should end flush with the X carriage plate, which allows a piece of metal to be glued on it, to trigger the endstop, since the extruder fan would otherwise collide with the X axis stepper before the carriage plate could touch the endstop and trigger it. All in all, it feels really rigid and it improved my input shaping compensation, compared to the previous mount. STEP file is attached, you're welcome to improve on my rough design. Cheers
