Remix of https://www.thingiverse.com/thing:4554557 by Emilostuff. Adapted for the components that I needed for my RC build. Removed the LCD screen, rotary encoder, and some of the mounting inside and added two 10K potentiometers.

Made for a Arduino Nano and a NRF24L01. The mounting block files are just hold-downs for both of these.

Knurled brass inserts were only used for the cover retention.

I did use just a few small support modifiers for the few holes in the sidewall of the bottom piece. Measures approx 6-1/4" X 4" X 1-1/8".
