Modular open sided Arduino Uno case

The 1" spacers can be shortened or lengthed as required. The Uno mounting holes are pilot holes that you will need to drill out to the diameter you need for the screws you want to use.
I've included a blank lid if you don't like the question mark.
I tried printing all four spacers at the same time and did not get a very clean print, since they are so small I'd suggest printing them one at a time using a brim.
