Multi ProTrinket mount (Arduinos)

I love Adafruit Pro-Trinkets. Sometimes a project needs more n' one. This was developed for the Dragon fire project that runs 720 NeoPixles. Worrying about memory and speed loss I just ran one Pro Trinket per 120 LED strip. Trinket 0 was the master but all of them had LEDs to manage. Worked out great and this was the super handy mount for the set.

Here's a clip of it running : https://youtu.be/bpcz8VtyUpU

Its set up to use 2 mm x 4-5 mm socket cap screws.
