This is my first thing! New to 3D Printing and rusty on the modeling, this is the first thing I've released with the hope that it alleviates someone else's frustrations with the cables dragging on the bed.
Designed in Fusion 360 in about 10 minutes, sliced with Cura 3.1.0, I designed this to hold the hotend assembly cabling off of my print bed and to remove the weight of the cable from my PTFE tube on my Sainsmart Creality Ender 3. I use this along with johnniewhiskey's cable chain https://www.thingiverse.com/thing:2920060. This part holds the cables snug using the bottom of the extrusion for retention and is loose enough for the cable to move freely in the Y and it clips to the extrusion firmly while also allowing for the part to move freely in the X.
I was able to print this with the following settings and it came out well. My first print was at 40% fan and the part came out solid with a little warping on the overhang for the cable cradle. Printing with full support leaves the cable cradle a bit rough and the stock cable sheath hangs up on it a little bit.
