Print Head Strain Relief Mount for JGAURORA A3S or A5 Wiring Harness Tube

thingiverse

I modified the design using Blender to minimize filament usage and reduce sharp edges. The addition of a dent at the top of the thicker part helps keep the plastic wiring conduit in place, though it still requires a zip tie for securement. The top section now tapers down to a thin point, allowing certain plastics to flex and absorb more strain than if the neck were entirely rigid. This alteration necessitates replacing the original screws with 2mm x 8mm screws (ACKET's photo in the comments shows his version using an 8.38mm screw including the head). However, Acket's photos of the installed item feature a flat plate on top, rendering the recesses for the screws unnecessary. Both versions add exactly 2mm when utilizing the recesses. ## Divergences from ACKET's Version - I moved the body down by 2.5mm to conserve plastic (the screw head recesses are now .5mm instead of 3mm) without affecting the overall height. - I re-sculpted the body. - I made the neck narrower for flexible or somewhat-flexible filaments. - See also "Changelog." This model is easy to install on the print head without disassembling anything. Simply unscrew the two bolts securing the restraining plate, pick up 2 new longer screws, and reinstall everything in its proper place. The tube holder is very reliable and rigid, unlike other models presented here. I highly recommend this part for manufacturing to all owners of this printer. I printed it using SBS plastic with 25% infill at 80mm/s, layer thickness 0.2mm, head temperature 250C, bed temperature 80C, cooling 50%, and no rafts or supports. -ACKET
