FlashForge Dreamer X-axis wire clip. The clip could be held just by pushing it onto the inside rib of the FlashForge Dreamer body, but I felt that since the X-axis motor wires move constantly, the clip deserved a more secure attachment.
Hence, I chose to tap the clip with an M3-0.5 thread and use an M3-0.5 x 8mm socket head machine screw. These screws of various lengths are used throughout the printer. I bought some off of eBay. Note that only the clip needs to be tapped, no modification to the printer's body is required.
Not wanting to modify the printer's body is the reason I did not want to use glue or sheet metal screws.
Printing is a challenge because of the small size of the clip. I used FlashForge white ABS. In my experience, the heat from the nozzle will concentrate and melt the clip. To overcome this problem I printed the clip inside a tall skirt (as tall as the clip itself, see pictures). In Simplify3D, this is accomplished by setting skirt layers to a deliberately high number (Simplify3D will not print the skirt higher than the part). The skirt was 6 outlines thick.
If I printed these clips today, I would use the variable fan speed firmware patch found at https://github.com/moonglow/flashforge_fan_fix. I talk more about it here.
Other settings were Simplify3D's default for Medium Quality ABS print at 0.2 mm layer height.
I used two clips. I first tapped the holes, then partly drove M3 machine screws into the clip, such that the screws did not go through the horizontal groove of the clip (that would prevent pushing the clips onto the rib).
With screws partly installed, I pushed X-axis motor wires into the clip. Then, I pushed the clips onto the rib inside FlashForge Dreamer, making sure I supported the plastic body of the printer on the outside with my palm (see pictures). The point here is not to stress and break the thin white side wall of your printer :)
Finally, I tightened the screws, just enough for the clips not to be able to slide off the rib. Do not over-tighten.
