This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/03dc4G2dDTX
After having a go at some Arduino LCD addons for a breadboard design,

I thought a box could be a good one to try.
ArduinoBox1... An LCD mounts in the box with an Arduino behind it.

Version 4 is bigger to allow a rotary encoder to be added. Above the LCD is a space for a strip of 8 addressable RGB LEDs. They will shine through a thin layer of the plastic.
Now all the screws holes are blind into the plastic so there are no screw heads on the front.
The addition of a screw hole in each corner allows a back to be fitted.

The ArduinoBox4_base https://www.tinkercad.com/things/58PAM3QtDOC-arduinobox4base/ will mount the box 4 onto the Arduino Breadboard in the "Arduino LCD addons" mentioned above.

Version 5 of the box (https://www.tinkercad.com/things/5HKtf6cLzZB-arduinobox5) is a slight mod of version 4 but now has the addressable LEDs centralized.

This is a follow on from some other Arduino things I've made.
