Enclosure for Small PCB and LED Matrix

This was made for a friend who wanted a waterproof box to hold a PCB and above it a LED matrix. It is printed in colourless PLA so the LED array can shine through the material in a diffused way. There are 4 posts inside to hold small self tapping screws to secure the PCB. The lid is a tight fit and futher versons will include a channel in the lid to hold a stretched O ring to make it 100% watertight. An extra file is added so you can clip the enclosure onto a small rod, frame etc. More clips wil
