So I have a topic asking about cutting the Walmart camping foam pad. Haven’t revisited that yet, because it won’t work for my application anyway. It’s a tad too translucent. I need something as a light buffer for this LED Nixie tube project:
So I really need something black, reasonably dense, and that cuts fairly well. Ideally should be between .25" and .5" thick. Anyone got a recommendation on what to get?
Keep in mind I do need to be able to cut relatively small holes (less than .25" in diameter) that end up pretty close to one another but can’t wallow out badly because then they’ll bleed light through.
