Tried the others, but they would not fit the servo tester I received. The others were not easy to print the text. So I made a new one that prints text mid layer (with a spool swap). Enjoy!
Screws are 2.5mm hex bolt

(ADDING A CAPACITOR)
I was having an issue with my servo tester not working with larger servos. Buttons would just flash and would not work. I added a 470uF capacitor to the input line. Fits perfectly in the 3D printed case. Solved all my servo issues. Works perfectly now. See Photos.
