shorter side replacements for acrylic Arduino UNO enclosure box

Original acrylic Arduino UNO box is cool, but it's also too high, and gets bad contact when a shield board is used due to short introduction.

These shorter replacement sides gets fully operational design, with very few important transparency loss.

You will need 2 pieces from the longest type (included single file as they are equal)

In the photo you can see 4 sets printed together (16 pieces).
