If you do a lot with servos this could be a handy tool to have on your shelf.

If so, the next step might be to simplify it and put it in a case of some sort. The prototype in this guide was built using Feather ecosystem components for ease of construction using the tripler wing. Since using 5v for the servo was a requirement, being battery powered wasn't. That makes it easy to switch to an ItsyBitsy M0 Express (it has no onboard battery support). The OLED display comes in a breakout version that's identical functionally to the FeatherWing for our purpose (it is just the display, no buttons). The level shifter and rotary encoder don't change.

The author anticipates doing this when he gets time to spend in Fusion360, so watch for an update if you are interested.
