To keep the dust out I’m using a removable acrylic cover to sit on top of the box.
This comprises of the following pieces of cut to size 4mm acrylic.
Tensol 12 was used to glue the sheets together.
Completed dust cover.
The dust cover sitting on the LED cube base.
.The protective film is still on the top piece of acrylic which is why it’s not as transparent as the sides.
