Kiss 24 amp ESC guards.
These fit my 24a Kiss ESC's after the ESC has had heat-shrink applied. I was using another version found here on Thingiverse but I had to slightly resize them to fit with the heat-shrink. That alone was no biggie but they were also kinda bulky.
I designed these a little lighter then some others found here on Thingiverse and I also only added one channel for the wire tie to save weight. V1 weighs in at 1.95g vs 3.7g for the ones I was previously using. I managed to save a total of 14.2g when including the wire ties.
Can use tape to secure as well.
I made three different designs identified by a version number. The photos include the version numbers to make it slightly easier to decide on what file to use and what one you like best.
Used on my Martian II frame.
May fit other ESC brands.
Enjoy, and may all your flights be smooth as silk.
