Like bubbles? Then you’ll love this 3D printed bubble blowing machine. It’s capable of blowing approximately 14,000 bubbles… per minute.
Designed and released on Thingiverse, the array of bubble orifices are 3D printed, as well as the gears and chain that rotate the belt of bubbles. The only thing not 3D printed is the 5 gallon bucket, some aluminum extrusion for mounting it rigidly, and the 50RPM motor that spins it around.
Place the bucket in your driveway, hook up a big fan behind it, and Bob’s your uncle — you’ve got 14,000 bubbles a minute to play with. Is it bad we want to see someone set this up inside a house?
If you want to get really fancy, you could also get a high-output fog machine to fill the bubbles with smoke for greater effect — or just make giant bubbles with this bubble producing machine inspired by the space program.
