I was getting frustrated with the lawnmower cable clips which grip the cable to the outside of the tube. I created these so that the cable was held inside the the cable clip, stopping it from popping out. I used the base settings for my ender 3 and printed in PLA. I am fairly sure they will work fine with any material and setting. I intend to make a slightly smaller diamter version for where the tubing thins out towards the bottom of the mower, but these still fit that part just a little looser.
