I recently needed a Dry Ice machine for some theatrical effects for a local show. Our budget would not stretch to hiring in a professional one so this is what I built instead. It’s mostly 3D printed, controlled remotely via bluetooth, battery powered, portable and includes LEDs for fun effect. You can even design your own nozzle to create different fog patterns.I’ve included two nozzle designs of my own for you to try.
It works great as a stage effect, and will be a hit at any Halloween parties.
