Modular open sided Arduino Uno case

The 1-inch spacers can be adjusted to any desired length. The Uno mounting holes are pre-drilled pilot holes that need to be enlarged to accommodate the chosen screws' diameters. A spare lid is included, should you prefer not to use the question mark. Printing all four spacers simultaneously resulted in a less-than-desirable outcome due to their small size; it's recommended to print them individually using a brim to achieve cleaner results.
