The basic things that you need in this project

use tape or anything to hold the lens

Make the inside walls of the box painted in black . "Because it blocks the light so u get a clear image "

Sometimes these do not work perfect as the big boys do I found a VIDEO that this guy puts some more efforts

And this look cool and perfect than the purchased diy, but the purchased kit lens is perfect than the  magnifier glass

Watch this video its perfect DESIGN and perfect diy 

But I thought beyond this what you can do I was impressed to see this video they combine a light to give more brightness

Which one you gonna choose its up to you enjoy stay safe and good
