I imported Rene's Skadis mount for the Engineer PA-09 crimpers into Onshape and made a copy to hold the Engineer PA-06 wire strippers. I have included two versions. One plain and one with embossed text (on the opposite side of the PA-09 crimper mount so you can place them next to each other and read the text on either side).
I have had good success printing the models as orientated using PrusaSlicer's organic supports on the buildplate only. The support within the slot pulls out super easily with tweezers or a skinny pair of needle nose pliers.
Note: Due to the shape of the jaws on the wire strippers they sit at a slight angle in the holder. If I made the slot wider they would sit straight, but be too loose to hold the strippers in place properly.
The author remixed this model.
