I don’t actually know how they do it in movies but from this one example I’m assuming it was industry standard but I could be wrong.

Other movies might do what you said e.g. airsoft gun or fake gun, with edited sounds later

I do find it hard to believe the industry standard is to use real guns with blanks but it may be that way. It’s a lot simpler, but obviously more dangerous

And yes guns are very loud, after a gun goes off beside you, you will have a sort of numbing in your ear for a few seconds and you can’t hear anything out of it lol

How would a fake gun make the sounds? Guess you could add in editing afterwards but the cleanest, easiest and most realistic would always be to use a real gun with blanks I would have thought. But I’m not a movie producer, so idk

Could also be that even if you’re able to get similar quality gun shots off a fake gun, it would cost a lot more in production etc

Also Im guessing you just printed the box, not the little black and red connectors, or the black piece that holds the screen or the little yellow buttons? Just wondering as I might try something similar some day.

True. Is it glued together or do the joints just hold it all together?

Very cool. Would you be worried at all about heat?
