Cable Chain Mounts (Ender 3 Pro x Micro Swiss Original Direct Drive Kit)

thingiverse

I wrote a huge description with a bunch of details but...it all got wiped. So, I'm gonna hope the pictures are enough explanation. All I'll add is: The main files are technically untested. After I finished putting mine together, I decided to make a few changes in response to my experience but I have not tested those changes. Mainly, I just reinforced where the drag chains mount to reduce snapping, Only place I can see this potentially being an issue is the X origin and terminus (might interfere with the extruder lever). The files I used for what you see in the picture are also included. I also don't know if the stock wiring harness works with these chains as I have a 500mm z-axis extension (I had to make my wires longer, but I don't know if you will have to). Every part has been designed with a face you can print on that minimizes overhangs. Unfortunately I don't know how to make files that are oriented right away, so mess around in your slicer to find that face. You need 10x20 drag chains (I used these: https://www.amazon.com/gp/product/B07SFFT1K5/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1) You will also need 2 M3 bolts (8-12mm long), washers, nuts, and adhesive for the nuts. The length varies because I never got the chance to fix the holes to be perfect; I just got it to work using 12mm bolts and a washer. You will also need to lift the printer at the four corners (I used these: https://www.thingiverse.com/thing:4571599). Theoretically you could get away without this by running the hotend harness above the aluminum extrusion that makes up the Ender 3's left base, but I haven't tested this. If you want to put the z drag chain where it "traditionally" goes (that is, behind the printer instead of on the front & side) you can find the origin I made here and the terminus here: https://www.thingiverse.com/thing:5550490.
