Y axis cable chain mount for Wanhao Di3 / Monoprice Maker Select v2.1

After installing a rear mount extruder fan shroud, I noticed that it frequently caught the heated bed cable. This led me to decide that I needed to install a cable chain to prevent further issues. However, most of the cable chain mounts available were either clip-on or bolted directly onto the heated bed. My main concern is that the heated bed mount can easily melt if I crank up the temperature for printing ABS. Therefore, I began brainstorming ways to create a cable management system without touching the heated bed. One solution was to utilize the square cut hole on the Y-axis plate instead of the heated bed itself. This particular design mounts onto the Y-axis plate and uses the square cut hole as a secure attachment point. To make use of this feature, I simply inserted it into the square hole and clipped it in place, securing it with a latch that fits snugly onto the edge of the plate. If your Maker Select v2.1 Y-axis plate does not have a square cut hole, then this mount is not suitable for your needs. However, if you do have this feature, I recommend using Sigismond0's cable chain design as a starting point for creating your own custom Y-axis mount end. Specifically, I used the LINK-45-out.stl, LINK-90-out.stl, and LINK-90-in.stl files from Sigismond0's design to create my cable chain. The cable chain has a slightly smaller bending radius than other configurations I've tried, making it easier to assemble without desoldering the wire ends. Additionally, it is wider and less prone to loose connections, which makes it a more reliable option for managing cables. I didn't make any modifications to the original design, so you can refer back to Sigismond0's files if needed. Since the heated bed mount was simply clipped onto the Y-axis plate without screws or glue, I experimented with different chain links to ensure that the cable stayed in place when the Y axis moved forward and backward. The 45-degree link allowed for bending in both directions, while the 90-degree link only bent one way. By playing with these options, I was able to force the cable to push downwards onto the plate, preventing it from popping out. So far, this solution has held up well and hasn't caused any issues, even at high temperatures. As a bonus, I've also created a horizontal version of this design that you can find on Thingiverse. **Print Settings** * Printer: Monoprice Maker Select v2.1 * Rafts: No * Supports: Yes * Infill: 20% * Notes: + Frame mount: Easy to print, no special instructions required. + Heated bed mount: Requires printing upside down with heavy use of support. **Post-Printing** * Frame mount: Remove the existing M3 screws for the Y motor mount and replace them with M3x10mm screws (original screws were too short). * Heated bed mount: Remove the heated bed, insert the square into the square cut hole on your Y-axis plate, clip it in place, and then reattach the heated bed. * Assemble the chains using Sigismond0's cable chain design.
