Ok. Wasnt sure if 1/4 would start to affect the photo quality. My eshopps looks like its 1/8” but im guessing thats more about keeping cost down. I have plenty of 1/4” clear cast to build one but thanks for the link. My local supplier is pretty expensive so a more cost effective option is always welcomeI stand corrected about the Orphek.
As far as acrylic, 1/4' is best considering that when you push down on the viewing box, you will get some pressure. Better to spend a couple more bucks and know your expensive smart phone is safer incase you made a faulty weld. This vendor is the cheapest I've found and they have great customer service. I get all my stuff from them.
