Guns with 3D-printed parts are rather unnerving, and 3D-printed hamburgers sound gross, but on the more fun side of the spectrum, 3D-printed bongs exist, and have been uploaded to MakerBot’s Thingiverse file-sharing hub. The most elaborate pieces feature embellishments like Super Mario and a skull, which have been downloaded 92 and 90 times, respectively.
The legality of printing your own paraphernalia might be in question here, but the bigger problem is whether these 3D-printed bongs actually work. It’s just plastic, right? Wouldn’t the bowl melt every time you try to light up?
