looking to see if anyone has a link to make a small lookdown viewer roughly 3" round only so it needs to be small. i want to use this for taking pictures in my small frag tank so i want it 3" diameter roughly and 3" tall. i was thinking of just taking some PVC and painting it black then just getting a piece of acrylic and using a jigsaw to cut it round and use some weld-on or some other acrylic bonder to seal it but i wasnt to sure if there is an easy way to do it or not.

the black paint is so it doesn't reflect the LEDS
