I came across a YouTube article a while ago to set up a print monitor via octoprint, so you can see what time you have left and the basics of what's going on with your print
Once set up it works over Wi-Fi and I think is a helpful little item rather than running back and forth to check on it or have your computer monitor running all the time.
You will need to print the case and be able to solder the four wires, you can use the screws or just use a small amount of hot glue to hold the board and Oled screen in place, you will need the Arduino ide to program it.
The Arduino software can be found here
I think the tutorials are self-explanatory and quite easy to understand, and getting to the finish line
