Z-Axis Chain Extruder-Side clip for Ender 3

thingiverse

<p>After printing johnniewhiskey's "Ender 3 Cable Chain ", I found that I didn't like that the cable chain didn't actually attach to the z-axis directly, so I set out looking for a part that would do this for me.</p> <p><a href="https://www.thingiverse.com/thing:3623342">Ender 3 - Cable Chain upgrade bracket mount - Extruder and Hotend - filament_guide</a> by <a href="https://www.thingiverse.com/djuanmurcia">djuanmurica</a> I found it overly-complex for what I needed. (I felt a chain to the hot-end was overkill and added unnecessary weight onto the z-axis...and no supports means reduced material waste, build time, and risk of breakage).</p> <p><a href="https://www.thingiverse.com/thing:3566939">Ender 3 extruder mount for cable chain</a> by <a href="https://www.thingiverse.com/ali1234">ali1234</a> This thing hit a bit closer to the mark as to what I was looking for, but there were some issues...for one, it didn't actually work with the v3 chain link. So I made my own that was heavily inspired by it.</p> <ul> <li>I made sure the chain fitting actually fit the <a href="https://cdn.thingiverse.com/assets/c6/b3/d0/60/f4/cableChain_link_v3.stl">cableChain_link_v3.stl</a> from <a href="https://www.thingiverse.com/johnniewhiskey">johnniewhiskey</a>'s <a href="https://www.thingiverse.com/thing:2920060/files">Ender 3 cable chain</a>.</li> <li>I moved the zip tie brackets around behind the extruder motor for improved aesthetics (you may find it easier to attach the part by pulling the motor off, or removing the entire z-axis bar from the z-stepper), and reduced to 2 holes for zip ties.</li> <li>I increased the size of the zip-tie holes (the ones on the original model didn't fit a standard 3 mm-width small zip tie).</li> <li>I removed the zip tie tie-down holes for the hot-end power cables, and instead designed the piece to fit the <a href="https://cdn.thingiverse.com/assets/3b/12/15/4e/f7/cableChain_XendCover.stl">cableChain_XendCover.stl</a> from <a href="https://www.thingiverse.com/johnniewhiskey">johnniewhiskey</a>'s <a href="https://www.thingiverse.com/thing:2920060/files">Ender 3 cable chain</a>.</li> <li>I flipped the tray to sit over the cables (to allow the ribbon cables and power cables to better interact with each other.</li> </ul>
