This Wahl clipper comes with some guards of different lengths, but not any long enough for my purposes. I have made 15 and 20-mm guards, but the Fusion 360 models allow for pretty easy creation of other lengths. It may be difficult to clip on and take off for a short time, but as it wears, it will get easier. The tight tolerances prevent it from slipping off as it wears. I have included all the design files I can think of, but if anyone wants a different file type, I am happy to export it.
The author marked this model as their own original creation.
