Like my other wall control remixes, here I use the DDD system and design a custom mount for something that's not provided in the parent.
This one is relatively generic, and I found that to get a good snug fit, it helps to cut a little adhesive felt strips (such as that used in anti-scratch floor kits for chairs) and adhere it to the plastic. This gives the holder just enough resistance to twisting motion so that the pliers don't fall out easily, but remain easy to put in and out. You can see the white felt in the picture above.
STEP file and matching left/right flats included.
